Globalisation and better standard of living plays an important role in transport energy demand. Recently, transport energy demand in Mauritius has increased significantly, thus leading to an abuse of natural resources and thereby contributing to global warming. Forecasting the transport energy demand is therefore important for controlling and managing the demand. In this paper, we develop a model to predict the transport energy demand. The model developed is based on a system of five stochastic differential equations (SDEs) consisting of five endogenous variables: fuel price, population, gross domestic product (GDP), number of vehicles and transport energy demand and three exogenous parameters: crude birth rate, crude death rate and labour force. An interval of seven years is used to avoid any falsification of result since Mauritius is a developing country. Data available for Mauritius from year 2003 up to 2009 are used to obtain the values of design variables by applying genetic algorithm. The model is verified and validated for 2010 to 2012 by substituting the values of coefficients obtained by GA in the model and using particle swarm optimisation (PSO) to predict the values of the exogenous parameters. This model will help to control the transport energy demand in Mauritius which will in turn foster Mauritius towards a pollution-free country and decrease our dependence on fossil fuels. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=genetic%20algorithm" title="genetic algorithm">genetic algorithm</a>, <a href="https://publications.waset.org/abstracts/search?q=modeling" title=" modeling"> modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=particle%20swarm%20optimization" title=" particle swarm optimization"> particle swarm optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=stochastic%20differential%20equations" title=" stochastic differential equations"> stochastic differential equations</a>, <a href="https://publications.waset.org/abstracts/search?q=transport%20energy%20demand" title="transport energy demand">transport energy demand</a> </p> <a href="https://publications.waset.org/abstracts/41078/an-integration-of-genetic-algorithm-and-particle-swarm-optimization-to-forecast-transport-energy-demand" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41078.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">369</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3474</span> Experimental and Numerical Analysis of Wood Pellet Breakage during Pneumatic Transport</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Julian%20Jaegers">Julian Jaegers</a>, <a href="https://publications.waset.org/abstracts/search?q=Siegmar%20Wirtz"> Siegmar Wirtz</a>, <a href="https://publications.waset.org/abstracts/search?q=Viktor%20Scherer"> Viktor Scherer</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Wood pellets belong to the most established trade formats of wood-based fuels. Especially, because of the transportability and the storage properties, but also due to low moisture content, high energy density, and the homogeneous particle size and shape, wood pellets are well suited for power generation in power plants and for the use in automated domestic firing systems. Before they are thermally converted, wood pellets pass various transport and storage procedures. There they undergo different mechanical impacts, which leads to pellet breakage and abrasion and to an increase in fines. The fines lead to operational problems during storage, charging, and discharging of pellets, they can increase the risk of dust explosions and can lead to pollutant emissions during combustion. In the current work, the dependence of the formation of fines caused by breakage during pneumatic transport is analyzed experimentally and numerically. The focus lies on the influence of conveying velocity, pellet loading, pipe diameter, and the shape of pipe components like bends or couplings. A test rig has been built, which allows the experimental evaluation of the pneumatic transport varying the above-mentioned parameters. Two high-speed cameras are installed for the quantitative optical access to the particle-particle and particle-wall contacts. The particle size distribution of the bulk before and after a transport process is measured as well as the amount of fines produced. The experiments will be compared with results of corresponding DEM/CFD simulations to provide information on contact frequencies and forces. The contribution proposed will present experimental results and report on the status of the DEM/CFD simulations. The final goal of the project is to provide a better insight into pellet breakage during pneumatic transport and to develop guidelines ensuring a more gentle transport. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=DEM%2FCFD-simulation%20of%20pneumatic%20conveying" title="DEM/CFD-simulation of pneumatic conveying">DEM/CFD-simulation of pneumatic conveying</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanical%20impact%20on%20wood%20pellets%20during%20transportation" title=" mechanical impact on wood pellets during transportation"> mechanical impact on wood pellets during transportation</a>, <a href="https://publications.waset.org/abstracts/search?q=pellet%20breakage" title=" pellet breakage"> pellet breakage</a>, <a href="https://publications.waset.org/abstracts/search?q=pneumatic%20transport%20of%20wood%20pellets" title=" pneumatic transport of wood pellets"> pneumatic transport of wood pellets</a> </p> <a href="https://publications.waset.org/abstracts/88559/experimental-and-numerical-analysis-of-wood-pellet-breakage-during-pneumatic-transport" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/88559.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">150</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3473</span> A Unified Model for Predicting Particle Settling Velocity in Pipe, Annulus and Fracture</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zhaopeng%20Zhu">Zhaopeng Zhu</a>, <a href="https://publications.waset.org/abstracts/search?q=Xianzhi%20Song"> Xianzhi Song</a>, <a href="https://publications.waset.org/abstracts/search?q=Gensheng%20Li"> Gensheng Li</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Transports of solid particles through the drill pipe, drill string-hole annulus and hydraulically generated fractures are important dynamic processes encountered in oil and gas well drilling and completion operations. Different from particle transport in infinite space, the transports of cuttings, proppants and formation sand are hindered by a finite boundary. Therefore, an accurate description of the particle transport behavior under the bounded wall conditions encountered in drilling and hydraulic fracturing operations is needed to improve drilling safety and efficiency. In this study, the particle settling experiments were carried out to investigate the particle settling behavior in the pipe, annulus and between the parallel plates filled with power-law fluids. Experimental conditions simulated the particle Reynolds number ranges of 0.01-123.87, the dimensionless diameter ranges of 0.20-0.80 and the fluid flow behavior index ranges of 0.48-0.69. Firstly, the wall effect of the annulus is revealed by analyzing the settling process of the particles in the annular geometry with variable inner pipe diameter. Then, the geometric continuity among the pipe, annulus and parallel plates was determined by introducing the ratio of inner diameter to an outer diameter of the annulus. Further, a unified dimensionless diameter was defined to confirm the relationship between the three different geometry in terms of the wall effect. In addition, a dimensionless term independent from the settling velocity was introduced to establish a unified explicit settling velocity model applicable to pipes, annulus and fractures with a mean relative error of 8.71%. An example case study was provided to demonstrate the application of the unified model for predicting particle settling velocity. This paper is the first study of annulus wall effects based on the geometric continuity concept and the unified model presented here will provide theoretical guidance for improved hydraulic design of cuttings transport, proppant placement and sand management operations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=wall%20effect" title="wall effect">wall effect</a>, <a href="https://publications.waset.org/abstracts/search?q=particle%20settling%20velocity" title=" particle settling velocity"> particle settling velocity</a>, <a href="https://publications.waset.org/abstracts/search?q=cuttings%20transport" title=" cuttings transport"> cuttings transport</a>, <a href="https://publications.waset.org/abstracts/search?q=proppant%20transport%20in%20fracture" title=" proppant transport in fracture"> proppant transport in fracture</a> </p> <a href="https://publications.waset.org/abstracts/141432/a-unified-model-for-predicting-particle-settling-velocity-in-pipe-annulus-and-fracture" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/141432.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">160</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3472</span> Molecular Dynamics Studies of Main Factors Affecting Mass Transport Phenomena on Cathode of Polymer Electrolyte Membrane Fuel Cell</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jingjing%20Huang">Jingjing Huang</a>, <a href="https://publications.waset.org/abstracts/search?q=Nengwei%20Li"> Nengwei Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Guanghua%20Wei"> Guanghua Wei</a>, <a href="https://publications.waset.org/abstracts/search?q=Jiabin%20You"> Jiabin You</a>, <a href="https://publications.waset.org/abstracts/search?q=Chao%20Wang"> Chao Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Junliang%20Zhang"> Junliang Zhang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this work, molecular dynamics (MD) simulation is applied to analyze the mass transport process in the cathode of proton exchange membrane fuel cell (PEMFC), of which all types of molecules situated in the cathode is considered. a reasonable and effective MD simulation process is provided, and models were built and compared using both Materials Studio and LAMMPS. The mass transport is one of the key issues in the study of proton exchange membrane fuel cells (PEMFCs). In this report, molecular dynamics (MD) simulation is applied to analyze the influence of Nafion ionomer distribution and Pt nano-particle size on mass transport process in the cathode. It is indicated by the diffusion coefficients calculation that a larger quantity of Nafion, as well as a higher equivalent weight (EW) value, will hinder the transport of oxygen. In addition, medium-sized Pt nano-particles (1.5~2nm) are more advantageous in terms of proton transport compared with other particle sizes (0.94~2.55nm) when the center-to-center distance between two Pt nano-particles is around 5 nm. Then mass transport channels are found to be formed between the hydrophobic backbone and the hydrophilic side chains of Nafion ionomer according to the radial distribution function (RDF) curves. And the morphology of these channels affected by the Pt size is believed to influence the transport of hydronium ions and, consequently the performance of PEMFC. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cathode%20catalytic%20layer" title="cathode catalytic layer">cathode catalytic layer</a>, <a href="https://publications.waset.org/abstracts/search?q=mass%20transport" title=" mass transport"> mass transport</a>, <a href="https://publications.waset.org/abstracts/search?q=molecular%20dynamics" title=" molecular dynamics"> molecular dynamics</a>, <a href="https://publications.waset.org/abstracts/search?q=proton%20exchange%20membrane%20fuel%20cell" title=" proton exchange membrane fuel cell"> proton exchange membrane fuel cell</a> </p> <a href="https://publications.waset.org/abstracts/160053/molecular-dynamics-studies-of-main-factors-affecting-mass-transport-phenomena-on-cathode-of-polymer-electrolyte-membrane-fuel-cell" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/160053.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">243</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3471</span> Analysis of Lift Force in Hydrodynamic Transport of a Finite Sized Particle in Inertial Microfluidics with a Rectangular Microchannel</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Xinghui%20Wu">Xinghui Wu</a>, <a href="https://publications.waset.org/abstracts/search?q=Chun%20Yang"> Chun Yang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Inertial microfluidics is a competitive fluidic method with applications in separation of particles, cells and bacteria. In contrast to traditional microfluidic devices with low Reynolds number, inertial microfluidics works in the intermediate Re number range which brings about several intriguing inertial effects on particle separation/focusing to meet the throughput requirement in the real-world. Geometric modifications to make channels become irregular shapes can leverage fluid inertia to create complex secondary flow for adjusting the particle equilibrium positions and thus enhance the separation resolution and throughput. Although inertial microfluidics has been extensively studied by experiments, our current understanding of its mechanisms is poor, making it extremely difficult to build rational-design guidelines for the particle focusing locations, especially for irregularly shaped microfluidic channels. Inertial particle microfluidics in irregularly shaped channels were investigated in our group. There are several fundamental issues that require us to address. One of them is about the balance between the inertial lift forces and the secondary drag forces. Also, it is critical to quantitatively describe the dependence of the life forces on particle-particle interactions in irregularly shaped channels, such as a rectangular one. To provide physical insights into the inertial microfluidics in channels of irregular shapes, in this work the immersed boundary-lattice Boltzmann method (IB-LBM) was introduced and validated to explore the transport characteristics and the underlying mechanisms of an inertial focusing single particle in a rectangular microchannel. The transport dynamics of a finitesized particle were investigated over wide ranges of Reynolds number (20 < Re < 500) and particle size. The results show that the inner equilibrium positions are more difficult to occur in the rectangular channel, which can be explained by the secondary flow caused by the presence of a finite-sized particle. Furthermore, force decoupling analysis was utilized to study the effect of each type of lift force on the inertia migration, and a theoretical model for the lateral lift force of a finite-sized particle in the rectangular channel was established. Such theoretical model can be used to provide theoretical guidance for the design and operation of inertial microfluidics. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=inertial%20microfluidics" title="inertial microfluidics">inertial microfluidics</a>, <a href="https://publications.waset.org/abstracts/search?q=particle%20focuse" title=" particle focuse"> particle focuse</a>, <a href="https://publications.waset.org/abstracts/search?q=life%20force" title=" life force"> life force</a>, <a href="https://publications.waset.org/abstracts/search?q=IB-LBM" title=" IB-LBM"> IB-LBM</a> </p> <a href="https://publications.waset.org/abstracts/163749/analysis-of-lift-force-in-hydrodynamic-transport-of-a-finite-sized-particle-in-inertial-microfluidics-with-a-rectangular-microchannel" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/163749.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">71</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3470</span> Phasor Measurement Unit Based on Particle Filtering</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rithvik%20Reddy%20Adapa">Rithvik Reddy Adapa</a>, <a href="https://publications.waset.org/abstracts/search?q=Xin%20Wang"> Xin Wang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Phasor Measurement Units (PMUs) are very sophisticated measuring devices that find amplitude, phase and frequency of various voltages and currents in a power system.

This leads to obtain the transport properties, such as viscosity and diffusion coefficient of a moderate dense gas. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=statistical%20mechanics" title="statistical mechanics">statistical mechanics</a>, <a href="https://publications.waset.org/abstracts/search?q=nonlocal%20separable%20potential" title=" nonlocal separable potential"> nonlocal separable potential</a>, <a href="https://publications.waset.org/abstracts/search?q=three-body%20interaction" title=" three-body interaction"> three-body interaction</a>, <a href="https://publications.waset.org/abstracts/search?q=faddeev%20equations" title=" faddeev equations"> faddeev equations</a> </p> <a href="https://publications.waset.org/abstracts/35738/quantum-statistical-mechanical-formulations-of-three-body-problems-via-non-local-potentials" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/35738.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">401</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3468</span> Transport of Inertial Finite-Size Floating Plastic Pollution by Ocean Surface Waves</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ross%20Calvert">Ross Calvert</a>, <a href="https://publications.waset.org/abstracts/search?q=Colin%20Whittaker"> Colin Whittaker</a>, <a href="https://publications.waset.org/abstracts/search?q=Alison%20Raby"> Alison Raby</a>, <a href="https://publications.waset.org/abstracts/search?q=Alistair%20G.%20L.%20Borthwick"> Alistair G.

Plastic pollution will have lasting effects because it is expected to take hundreds or thousands of years for plastic to decay in the ocean. The question arises how waves transport plastic in the ocean. The predominant motion induced by waves creates ellipsoid orbits. However, these orbits do not close, resulting in a drift. This is defined as Stokes drift. If a particle is infinitesimally small and the same density as water, it will behave exactly as the water does, i.e., as a purely Lagrangian tracer. However, as the particle grows in size or changes density, it will behave differently. The particle will then have its own inertia, the fluid will exert drag on the particle, because there is relative velocity, and it will rise or sink depending on the density and whether it is on the free surface. Previously, plastic pollution has all been considered to be purely Lagrangian. However, the steepness of waves in the ocean is small, normally about α = k₀a = 0.1 (where k₀ is the wavenumber and a is the wave amplitude), this means that the mean drift flows are of the order of ten times smaller than the oscillatory velocities (Stokes drift is proportional to steepness squared, whilst the oscillatory velocities are proportional to the steepness). Thus, the particle motion must have the forces of the full motion, oscillatory and mean flow, as well as a dynamic buoyancy term to account for the free surface, to determine whether inertia is important. To track the motion of a floating inertial particle under wave action requires the fluid velocities, which form the forcing, and the full equations of motion of a particle to be solved. Starting with the equation of motion of a sphere in unsteady flow with viscous drag. Terms can added then be added to the equation of motion to better model floating plastic: a dynamic buoyancy to model a particle floating on the free surface, quadratic drag for larger particles and a slope sliding term. Using perturbation methods to order the equation of motion into sequentially solvable parts allows a parametric equation for the transport of inertial finite-sized floating particles to be derived. This parametric equation can then be validated using numerical simulations of the equation of motion and flume experiments. This paper presents a parametric equation for the transport of inertial floating finite-size particles by ocean waves. The equation shows an increase in Stokes drift for larger, less dense particles. The equation has been validated using numerical solutions of the equation of motion and laboratory flume experiments. The difference in the particle transport equation and a purely Lagrangian tracer is illustrated using worlds maps of the induced transport. This parametric transport equation would allow ocean-scale numerical models to include inertial effects of floating plastic when predicting or tracing the transport of pollutants. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=perturbation%20methods" title="perturbation methods">perturbation methods</a>, <a href="https://publications.waset.org/abstracts/search?q=plastic%20pollution%20transport" title=" plastic pollution transport"> plastic pollution transport</a>, <a href="https://publications.waset.org/abstracts/search?q=Stokes%20drift" title=" Stokes drift"> Stokes drift</a>, <a href="https://publications.waset.org/abstracts/search?q=wave%20flume%20experiments" title=" wave flume experiments"> wave flume experiments</a>, <a href="https://publications.waset.org/abstracts/search?q=wave-induced%20mean%20flow" title=" wave-induced mean flow"> wave-induced mean flow</a> </p> <a href="https://publications.waset.org/abstracts/111423/transport-of-inertial-finite-size-floating-plastic-pollution-by-ocean-surface-waves" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/111423.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">121</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3467</span> Micro- and Nanoparticle Transport and Deposition in Elliptic Obstructed Channels by Lattice Boltzmann Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Salman%20Piri">Salman Piri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, a two-dimensional lattice Boltzmann method (LBM) was considered for the numerical simulation of fluid flow in a channel. Also, the Lagrangian method was used for particle tracking in one-way coupling. Three hundred spherical particles with specific diameters were released in the channel entry and an elliptical object was placed in the channel for flow obstruction. The effect of gravity, the drag force, the Saffman lift and the Brownian forces were evaluated in the particle motion trajectories. Also, the effect of the geometrical parameter, ellipse aspect ratio, and the flow characteristic or Reynolds number was surveyed for the transport and deposition of particles. Moreover, the influence of particle diameter between 0.01 and 10 µm was investigated. Results indicated that in small Reynolds, more inertial and gravitational trapping occurred on the obstacle surface for particles with larger diameters. Whereas, for nano-particles, influenced by Brownian diffusion and vortices behind the obstacle, the inertial and gravitational mechanisms were insignificant and diffusion was the dominant deposition mechanism. In addition, in Reynolds numbers larger than 400, there was no significant difference between the deposition of finer and larger particles. Also, in higher aspect ratios of the ellipse, more inertial trapping occurred for particles of larger diameter (10 micrometers), while in lower cases, interception and gravitational mechanisms were dominant. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ellipse%20aspect%20elito" title="ellipse aspect elito">ellipse aspect elito</a>, <a href="https://publications.waset.org/abstracts/search?q=particle%20tracking%20diffusion" title=" particle tracking diffusion"> particle tracking diffusion</a>, <a href="https://publications.waset.org/abstracts/search?q=lattice%20boltzman%20method" title=" lattice boltzman method"> lattice boltzman method</a>, <a href="https://publications.waset.org/abstracts/search?q=larangain%20particle%20tracking" title=" larangain particle tracking"> larangain particle tracking</a> </p> <a href="https://publications.waset.org/abstracts/168547/micro-and-nanoparticle-transport-and-deposition-in-elliptic-obstructed-channels-by-lattice-boltzmann-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/168547.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">79</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3466</span> 3D Modeling of Flow and Sediment Transport in Tanks with the Influence of Cavity</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Terfous">A.

One key aspect is to propose optimized designs for detention tanks in order to best reduce flood peak flows and in the meantime settle particles. It is, therefore, necessary to understand complex flows patterns and sediment deposition conditions in stormwater detention basins. The aim of this paper is to study flow structure and particle deposition pattern for a given tank geometry in view to control and maximize sediment deposition. Both numerical simulation and experimental works were done to investigate the flow and sediment distribution in a storm tank with a cavity. As it can be indicated, the settle distribution of the particle in a rectangular tank is mainly determined by the flow patterns and the bed shear stress. The flow patterns in a rectangular tank differ with different geometry, entrance flow rate and the water depth. With the changing of flow patterns, the bed shear stress will change respectively, which also play an influence on the particle settling. The accumulation of the particle in the bed changes the conditions at the bottom, which is ignored in the investigations, however it worth much more attention, the influence of the accumulation of the particle on the sedimentation should be important. The approach presented here is based on the resolution of the Reynolds averaged Navier-Stokes equations to account for turbulent effects and also a passive particle transport model. An analysis of particle deposition conditions is presented in this paper in terms of flow velocities and turbulence patterns. Then sediment deposition zones are presented thanks to the modeling with particle tracking method. It is shown that two recirculation zones seem to significantly influence sediment deposition. Due to the possible overestimation of particle trap efficiency with standard wall functions and stick conditions, further investigations seem required for basal boundary conditions based on turbulent kinetic energy and shear stress. These observations are confirmed by experimental investigations processed in the laboratory. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=storm%20sewers" title="storm sewers">storm sewers</a>, <a href="https://publications.waset.org/abstracts/search?q=sediment%20deposition" title=" sediment deposition"> sediment deposition</a>, <a href="https://publications.waset.org/abstracts/search?q=numerical%20simulation" title=" numerical simulation"> numerical simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=experimental%20investigation" title=" experimental investigation"> experimental investigation</a> </p> <a href="https://publications.waset.org/abstracts/69352/3d-modeling-of-flow-and-sediment-transport-in-tanks-with-the-influence-of-cavity" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/69352.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">325</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3465</span> The Pressure Losses in the Model of Human Lungs</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Michaela%20Chovancova">Michaela Chovancova</a>, <a href="https://publications.waset.org/abstracts/search?q=Pavel%20Niedoba"> Pavel Niedoba</a> </p> <p class="card-text"><strong>Abstract:</strong></p> For the treatment of acute and chronic lung diseases it is preferred to deliver medicaments by inhalation.

The transport of aerosol particles in the particular part of the lung is influenced by their size, anatomy of the lungs, breathing pattern and airway resistance. This article deals with calculation of airway resistance in the lung model of Horsfield. It solves the problem of determination of the pressure losses in bifurcation and thus defines the pressure drop at a given location in the bronchial tree.

The critical supersaturation and the variation of the growth performance with supersaturation for high-concentration particles were measured by a flow cloud chamber. Findings suggest that the influence of particle concentration on the growth performance will reduce with the increase of supersaturation. Reducing residence time and increasing particle concentration have similar effects on the growth performance of the high-concentration particle group. Increasing particle concentration and shortening residence time will increase the critical supersaturation of the particle group. The critical supersaturation required to activate a high-concentration particle group is lower than that of the single-particle when the minimum particle size in the particle group is the same as that of a single particle. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sub-micron%20particles" title="sub-micron particles">sub-micron particles</a>, <a href="https://publications.waset.org/abstracts/search?q=heterogeneous%20condensation" title=" heterogeneous condensation"> heterogeneous condensation</a>, <a href="https://publications.waset.org/abstracts/search?q=critical%20supersaturation" title=" critical supersaturation"> critical supersaturation</a>, <a href="https://publications.waset.org/abstracts/search?q=nucleation" title=" nucleation"> nucleation</a> </p> <a href="https://publications.waset.org/abstracts/147194/growth-performance-and-critical-supersaturation-of-heterogeneous-condensation-for-high-concentration-of-insoluble-sub-micron-particles" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/147194.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">157</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3463</span> Modeling Of The Random Impingement Erosion Due To The Impact Of The Solid Particles</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Siamack%20A.%20Shirazi">Siamack A.

Such particles interact with the pipe material and cause erosion which threats the integrity of the system. Therefore, predicting the erosion rate is an important factor in the design and the monitor of such systems. Mechanistic models can provide reliable predictions for many conditions while demanding only relatively low computational cost. Mechanistic models utilize a representative particle trajectory to predict the impact characteristics of the majority of the particle impacts that cause maximum erosion rate in the domain. The erosion caused by particle impacts is not only due to the direct impacts but also random impingements. In the present study, an alternative model has been introduced to describe the erosion due to random impingement of particles. The present model provides a realistic trend for erosion with changes in the particle size and particle Stokes number. The present model is examined against the experimental data and CFD simulation results and indicates better agreement with the data incomparison to the available models in the literature. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=erosion" title="erosion">erosion</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanistic%20modeling" title=" mechanistic modeling"> mechanistic modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=particles" title=" particles"> particles</a>, <a href="https://publications.waset.org/abstracts/search?q=multiphase%20flow" title=" multiphase flow"> multiphase flow</a>, <a href="https://publications.waset.org/abstracts/search?q=gas-liquid-solid" title=" gas-liquid-solid"> gas-liquid-solid</a> </p> <a href="https://publications.waset.org/abstracts/144301/modeling-of-the-random-impingement-erosion-due-to-the-impact-of-the-solid-particles" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/144301.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">168</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3462</span> Low-Cost Reusable Thermal Energy Storage Particle for Concentrating Solar Power</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kyu%20Bum%20Han">Kyu Bum Han</a>, <a href="https://publications.waset.org/abstracts/search?q=Eunjin%20Jeon"> Eunjin Jeon</a>, <a href="https://publications.waset.org/abstracts/search?q=Kimberly%20Watts"> Kimberly Watts</a>, <a href="https://publications.waset.org/abstracts/search?q=Brenda%20Payan%20Medina"> Brenda Payan Medina</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Gen3 Concentrating Solar Power (CSP) high-temperature thermal systems have the potential to lower the cost of a CSP system. When compared to the other systems (chloride salt blends and supercritical fluids), the particle transport system can avoid many of the issues associated with high fluid temperature systems at high temperature because of its ability to operate at ambient pressure with limited corrosion or thermal stability risk. Furthermore, identifying and demonstrating low-cost particles that have excellent optical properties and durability can significantly reduce the levelized cost of electricity (LCOE) of particle receivers. The currently available thermal transfer particle in the study and market is oxidized at about 700oC, which reduces its durability, generates particle loss by high friction loads, and causes the color change. To meet the CSP SunShot goal, the durability of particles must be improved by identifying particles that are less abrasive to other structural materials. Furthermore, the particles must be economically affordable and the solar absorptance of the particles must be increased while minimizing thermal emittance. We are studying a novel thermal transfer particle, which has low cost, high durability, and high solar absorptance at high temperatures. The particle minimizes thermal emittance and will be less abrasive to other structural materials. Additionally, the particle demonstrates reusability, which significantly lowers the LCOE. This study will contribute to two principal disciplines of energy science: materials synthesis and manufacturing. Developing this particle for thermal transfer will have a positive impact on the ceramic study and industry as well as the society. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=concentrating%20solar%20power" title="concentrating solar power">concentrating solar power</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20energy%20storage" title=" thermal energy storage"> thermal energy storage</a>, <a href="https://publications.waset.org/abstracts/search?q=particle" title=" particle"> particle</a>, <a href="https://publications.waset.org/abstracts/search?q=reusability" title=" reusability"> reusability</a>, <a href="https://publications.waset.org/abstracts/search?q=economics" title=" economics"> economics</a> </p> <a href="https://publications.waset.org/abstracts/141959/low-cost-reusable-thermal-energy-storage-particle-for-concentrating-solar-power" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/141959.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">222</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3461</span> Particle Concentration Distribution under Idling Conditions in a Residential Underground Garage</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yu%20Zhao">Yu Zhao</a>, <a href="https://publications.waset.org/abstracts/search?q=Shinsuke%20Kato"> Shinsuke Kato</a>, <a href="https://publications.waset.org/abstracts/search?q=Jianing%20Zhao"> Jianing Zhao</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Particles exhausted from cars have an adverse impacts on human health.

Success prerequisite of this form of cargo carriage is not technologic decision, but the comprehensive attitude towards it. Integration of the transport industry must refer to both technical and organizational-economic fields. Support of the multimodal’s must be the priority of the transport policy in different organizations of Europe and Asia. The method of approach to the transport as a unified system has been changed to a certain extent in the market conditions. Nowadays the competition between the different kinds of transport is not to be considered as a competition of one kind of transport towards another one, but is to be considered as a stimulator of the transport development. Basically, transport logistic, as the recent methodology and organization of the rationally flow of cargos at the specialized logistic centres during their procession provides effective rise of such flow of cargos, decreases non-operating expenses and gives the opportunity to the transport companies to come along with the time, to meet market clients’ requirements.

The traditional monitoring method in Hungary is obsolete but using indirect measurement devices and techniques like optical backscatter sensors (OBS), laser diffraction or acoustic backscatter sensors (ABS) could provide a fast and efficient alternative option of direct methods. However, these methods are strongly sensitive to the particle characteristics (i.e. particle shape, particle size and mineral composition). The current method does not provide sufficient information about particle size distribution, mineral analysis is rarely done, and the shape of the suspended sediment particles have not been examined yet. The aims of the study are (1) to determine the particle characterisation of suspended sediment in the Danube River using advanced particle characterisation methods as laser diffraction and automated imaging, and (2) to perform a sensitivity analysis of the indirect methods in order to determine the impact of suspended particle characteristics. The particle size distribution is determined by laser diffraction. The particle shape and mineral composition analysis is done by the Morphologi G3ID image analyser. The investigated indirect measurement devices are the LISST-Portable|XR, the LISST-ABS (Sequoia Inc.) and the Rio Grande 1200 kHz ADCP (Teledyne Marine). The major findings of this study are (1) the statistical shape of the suspended sediment particle - this is the first research in this context, (2) the actualised particle size distribution – that can be compared to historical information, so that the morphological changes can be tracked, (3) the actual mineral composition of the suspended sediment in the Danube River, and (4) the reliability of the tested indirect methods has been increased – based on the results of the sensitivity analysis and the previous findings. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=advanced%20particle%20characterisation" title="advanced particle characterisation">advanced particle characterisation</a>, <a href="https://publications.waset.org/abstracts/search?q=automated%20imaging" title=" automated imaging"> automated imaging</a>, <a href="https://publications.waset.org/abstracts/search?q=indirect%20methods" title=" indirect methods"> indirect methods</a>, <a href="https://publications.waset.org/abstracts/search?q=laser%20diffraction" title=" laser diffraction"> laser diffraction</a>, <a href="https://publications.waset.org/abstracts/search?q=mineral%20composition" title=" mineral composition"> mineral composition</a>, <a href="https://publications.waset.org/abstracts/search?q=suspended%20sediment" title=" suspended sediment"> suspended sediment</a> </p> <a href="https://publications.waset.org/abstracts/118731/advanced-particle-characterisation-of-suspended-sediment-in-the-danube-river-using-automated-imaging-and-laser-diffraction" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/118731.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">146</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3458</span> Predicting the Effect of Silicon Electrode Design Parameters on Thermal Performance of a Lithium-Ion Battery</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Harika%20Dasari">Harika Dasari</a>, <a href="https://publications.waset.org/abstracts/search?q=Eric%20Eisenbraun"> Eric Eisenbraun</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The present study models the role of electrode structural characteristics on the thermal behavior of lithium-ion batteries.

The study also considered the tissue tension in the model to demonstrate the effect of lung. Tissue tensions are transferred by the lung parenchyma and produce the pressure gradient. This load expands the alveoli and establishes a sub-ambient (vacuum) pressure within the lungs. Thus, at the alveolar level, the flow field and movement of alveoli wall lead to an integrated effect. In this research, we assume that the three-dimensional alveolus has a visco-elastic tissue (walls). For accurate investigation of pulmonary tissue mechanical properties on particle transport and alveolar flow field, the actual relevance between tissue movement and airflow is solved by two-way FSI (Fluid Structure Interaction) simulation technique in the alveolus. Therefore, the essence of real simulation of pulmonary breathing mechanics can be achieved by developing a coupled FSI computational model. We, therefore conduct a series of FSI simulations over a range of tissue models and breathing rates. As a result, the fluid flows and streamlines have changed during present flexible model against the rigid models and also the two-way coupling particle trajectories have changed against the one-way particle coupling. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=FSI" title="FSI">FSI</a>, <a href="https://publications.waset.org/abstracts/search?q=two-way%20particle%20coupling" title=" two-way particle coupling"> two-way particle coupling</a>, <a href="https://publications.waset.org/abstracts/search?q=alveoli" title=" alveoli"> alveoli</a>, <a href="https://publications.waset.org/abstracts/search?q=CDF" title=" CDF"> CDF</a> </p> <a href="https://publications.waset.org/abstracts/54790/the-utilization-of-fsi-technique-and-two-way-particle-coupling-system-on-particle-dynamics-in-the-human-alveoli" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/54790.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">257</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3456</span> Implementing a Mobility Platform to Connect Hubs in Rural Areas</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=E.%20Neidhardt">E.

They must buy food, get to work, or go to the doctor. Many people are dependent on public transport to satisfy their needs. Especially in rural areas with a low population density this is difficult. In these areas it is often not cost-effective to provide public transport with sufficient coverage and frequency. Therefore, the available public transport is unattractive. As a result, people use their own car, which is not desirable from a sustainable point of view. Children and some elderly people also do not have this option. Sometimes people organize themselves and volunteer transport services are created, which function similarly to the demand-oriented taxis. With a platform for demand-oriented transport, we want to make the available public transport more usable and attractive by linking scheduled transport with voluntary transport services. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=demand-oriented" title="demand-oriented">demand-oriented</a>, <a href="https://publications.waset.org/abstracts/search?q=HubChain" title=" HubChain"> HubChain</a>, <a href="https://publications.waset.org/abstracts/search?q=living%20lab" title=" living lab"> living lab</a>, <a href="https://publications.waset.org/abstracts/search?q=public%20transport" title=" public transport"> public transport</a> </p> <a href="https://publications.waset.org/abstracts/134336/implementing-a-mobility-platform-to-connect-hubs-in-rural-areas" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/134336.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">223</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3455</span> Solid Particles Transport and Deposition Prediction in a Turbulent Impinging Jet Using the Lattice Boltzmann Method and a Probabilistic Model on GPU</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ali%20Abdul%20Kadhim">Ali Abdul Kadhim</a>, <a href="https://publications.waset.org/abstracts/search?q=Fue%20Lien"> Fue Lien</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Solid particle distribution on an impingement surface has been simulated utilizing a graphical processing unit (GPU). In-house computational fluid dynamics (CFD) code has been developed to investigate a 3D turbulent impinging jet using the lattice Boltzmann method (LBM) in conjunction with large eddy simulation (LES) and the multiple relaxation time (MRT) models. This paper proposed an improvement in the LBM-cellular automata (LBM-CA) probabilistic method. In the current model, the fluid flow utilizes the D3Q19 lattice, while the particle model employs the D3Q27 lattice. The particle numbers are defined at the same regular LBM nodes, and transport of particles from one node to its neighboring nodes are determined in accordance with the particle bulk density and velocity by considering all the external forces. The previous models distribute particles at each time step without considering the local velocity and the number of particles at each node. The present model overcomes the deficiencies of the previous LBM-CA models and, therefore, can better capture the dynamic interaction between particles and the surrounding turbulent flow field. Despite the increasing popularity of LBM-MRT-CA model in simulating complex multiphase fluid flows, this approach is still expensive in term of memory size and computational time required to perform 3D simulations. To improve the throughput of each simulation, a single GeForce GTX TITAN X GPU is used in the present work. The CUDA parallel programming platform and the CuRAND library are utilized to form an efficient LBM-CA algorithm. The methodology was first validated against a benchmark test case involving particle deposition on a square cylinder confined in a duct. The flow was unsteady and laminar at Re=200 (Re is the Reynolds number), and simulations were conducted for different Stokes numbers. The present LBM solutions agree well with other results available in the open literature. The GPU code was then used to simulate the particle transport and deposition in a turbulent impinging jet at Re=10,000. The simulations were conducted for L/D=2,4 and 6, where L is the nozzle-to-surface distance and D is the jet diameter. The effect of changing the Stokes number on the particle deposition profile was studied at different L/D ratios. For comparative studies, another in-house serial CPU code was also developed, coupling LBM with the classical Lagrangian particle dispersion model. Agreement between results obtained with LBM-CA and LBM-Lagrangian models and the experimental data is generally good. The present GPU approach achieves a speedup ratio of about 350 against the serial code running on a single CPU. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CUDA" title="CUDA">CUDA</a>, <a href="https://publications.waset.org/abstracts/search?q=GPU%20parallel%20programming" title=" GPU parallel programming"> GPU parallel programming</a>, <a href="https://publications.waset.org/abstracts/search?q=LES" title=" LES"> LES</a>, <a href="https://publications.waset.org/abstracts/search?q=lattice%20Boltzmann%20method" title=" lattice Boltzmann method"> lattice Boltzmann method</a>, <a href="https://publications.waset.org/abstracts/search?q=MRT" title=" MRT"> MRT</a>, <a href="https://publications.waset.org/abstracts/search?q=multi-phase%20flow" title=" multi-phase flow"> multi-phase flow</a>, <a href="https://publications.waset.org/abstracts/search?q=probabilistic%20model" title=" probabilistic model"> probabilistic model</a> </p> <a href="https://publications.waset.org/abstracts/77795/solid-particles-transport-and-deposition-prediction-in-a-turbulent-impinging-jet-using-the-lattice-boltzmann-method-and-a-probabilistic-model-on-gpu" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/77795.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">207</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3454</span> Development of 3D Particle Method for Calculating Large Deformation of Soils </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sung-Sik%20Park">Sung-Sik Park</a>, <a href="https://publications.waset.org/abstracts/search?q=Han%20Chang"> Han Chang</a>, <a href="https://publications.waset.org/abstracts/search?q=Kyung-Hun%20Chae"> Kyung-Hun Chae</a>, <a href="https://publications.waset.org/abstracts/search?q=Sae-Byeok%20Lee"> Sae-Byeok Lee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, a three-dimensional (3D) Particle method without using grid was developed for analyzing large deformation of soils instead of using ordinary finite element method (FEM) or finite difference method (FDM).

The Mohr-Coulomb failure criterion was incorporated into the 3D Particle method to determine soil failure. The yielding and hardening behavior of soil before failure was also considered by varying viscosity of soil. First of all, an unconfined compression test was carried out and the large deformation following soil yielding or failure was simulated by the developed 3D Particle method. The results were also compared with those of a commercial FEM software PLAXIS 3D.

The soft particle is coated with a positively charged polyelectrolyte layer (PEL) and the rigid core is having a uniform surface charge density. The Darcy-Brinkman extended Navier-Stokes equations are solved for the motion of the ionized fluid, the non-linear Nernst-Planck equations for the ion transport and the Poisson equation for the electric potential. A pressure correction based iterative algorithm is adopted for numerical computations. The effects of convection on double layer polarization (DLP) and diffusion dominated counter ions penetration are investigated for a wide range of Debye layer thickness, PEL fixed surface charge density, and permeability of the PEL. Our results show that when the Debye layer is in order of the particle size, the DLP effect is significant and produces a reduction in electrophoretic mobility. However, the double layer polarization effect is negligible for a thin Debye layer or low permeable cases.

Conventional wisdom is to present an easy to handle tool for planners, managers and decision makers towards pricing policy effectiveness and demand attractiveness, appropriate to use for other similar cases. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=competitor%20analysis" title="competitor analysis">competitor analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=transport%20economics" title=" transport economics"> transport economics</a>, <a href="https://publications.waset.org/abstracts/search?q=transport%20generalized%20cost" title=" transport generalized cost"> transport generalized cost</a>, <a href="https://publications.waset.org/abstracts/search?q=quantitative%20modelling" title=" quantitative modelling"> quantitative modelling</a> </p> <a href="https://publications.waset.org/abstracts/80755/competitor-analysis-to-quantify-the-benefits-and-for-different-use-of-transport-infrastructure" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/80755.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">247</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3449</span> A Review of the Fundamental Principles of the National Transport Policy and Developmental Implementation Programmes</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Charles%20Asenime">Charles Asenime</a>, <a href="https://publications.waset.org/abstracts/search?q=Asaju%20Joel"> Asaju Joel</a>, <a href="https://publications.waset.org/abstracts/search?q=Fagbenro%20Abiola"> Fagbenro Abiola</a>, <a href="https://publications.waset.org/abstracts/search?q=Adetoyese%20Oguntimehin"> Adetoyese Oguntimehin</a>, <a href="https://publications.waset.org/abstracts/search?q=Agosu%20Rebecca"> Agosu Rebecca</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper examines the fundamental principles of the National Transport Policy (NTP) and determined its role in the execution of transport projects, and the establishment of ministries, departments, and agencies. Data used for the paper are from secondary sources of commissioned reports, studies, internet sources, and government releases. Results of the analysis show that the draft NTP has been used to establish transport schemes, master plans, and transport infrastructure. The paper concludes that though, the national transport Policy is still in a draft form, its production, however, has shaped the transport system in Nigeria and has shown how transport has improved the economy through the efficient utilisation of resources, improved mobility, and lifestyle. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=principles" title="principles">principles</a>, <a href="https://publications.waset.org/abstracts/search?q=draft" title=" draft"> draft</a>, <a href="https://publications.waset.org/abstracts/search?q=system" title=" system"> system</a>, <a href="https://publications.waset.org/abstracts/search?q=resources" title=" resources"> resources</a> </p> <a href="https://publications.waset.org/abstracts/168700/a-review-of-the-fundamental-principles-of-the-national-transport-policy-and-developmental-implementation-programmes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/168700.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">141</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3448</span> Basic Properties of a Fundamental Particle: Behavioral-Physical and Visual Methods for the Study of Fundamental Particle</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shukran%20M.%20Dadayev">Shukran M. Dadayev</a> </p> <p class="card-text"><strong>Abstract:</strong></p> To author's best knowledge, in this paper, the Basic Properties and Research methods of a Fundamental Particle is studied for the first time. That's to say, Fundamental Particle has not been discovered in the Nature yet. Because Fundamental Particle consists of specific Physical, Geometrical and Internal bases. Geometrical and Internal characteristics that are considered significant for the elementary and fundamental particles aren’t basic properties, characteristics or criteria of a Fundamental Particle. Of course, completely new Physical and Visual experimental methods of Quantum mechanics and Behavioral-Physical investigations of Particles are needed to study and discover the Fundamental Particle. These are new Physical, Visual and Behavioral-Physical experimental methods for describing and discovering the Fundamental Particle in the Nature and Microworld. Fundamental Particle consists of the same Energy-Mass-Motion system and a symmetry of Energy-Mass-Motion. Fundamental Particle supplies each of the elementary particles with the same Energy-Mass-Motion system at the same time and regulates each of the particles. Fundamental Particle gives Energy, Mass and Motion to each particles at the same time, each of the Particles consists of acquired Energy-Mass-Motion system and symmetry. Energy, Mass, Motion given by the Fundamental Particle to the particles are Symmetrical Equivalent and they remain in their primary shapes in all cases. Fundamental Particle gives Energy-Mass-Motion system and symmetry consisting of different measures and functions to each of the particles. The Motion given by the Fundamental Particle to the particles is Gravitation, Gravitational Interaction not only gives Motion, but also cause Motion by attracting. All Substances, Fields and Cosmic objects consist of Energy-Mass-Motion. The Field also includes specific Mass. They are always Energetic, Massive and Active. Fundamental Particle establishes the bases of the Nature. Supplement and Regulating of all the particles existing in the Nature belongs to Fundamental Particle. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=basic%20properties%20of%20a%20fundamental%20particle" title="basic properties of a fundamental particle">basic properties of a fundamental particle</a>, <a href="https://publications.waset.org/abstracts/search?q=behavioral-physical%20and%20visual%20methods" title=" behavioral-physical and visual methods"> behavioral-physical and visual methods</a>, <a href="https://publications.waset.org/abstracts/search?q=energy-mass-motion%20system%20and%20symmetrical%20equivalence" title=" energy-mass-motion system and symmetrical equivalence"> energy-mass-motion system and symmetrical equivalence</a>, <a href="https://publications.waset.org/abstracts/search?q=fundamental%20particle" title=" fundamental particle"> fundamental particle</a> </p> <a href="https://publications.waset.org/abstracts/94061/basic-properties-of-a-fundamental-particle-behavioral-physical-and-visual-methods-for-the-study-of-fundamental-particle" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/94061.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">3725</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3447</span> Effect of Bi-Dispersity on Particle Clustering in Sedimentation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ali%20Abbas%20Zaidi">Ali Abbas Zaidi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In free settling or sedimentation, particles form clusters at high Reynolds number and dilute suspensions. It is due to the entrapment of particles in the wakes of upstream particles. In this paper, the effect of bi-dispersity of settling particles on particle clustering is investigated using particle-resolved direct numerical simulation. Immersed boundary method is used for particle fluid interactions and discrete element method is used for particle-particle interactions. The solid volume fraction used in the simulation is 1% and the Reynolds number based on Sauter mean diameter is 350. Both solid volume fraction and Reynolds number lie in the clustering regime of sedimentation. In simulations, the particle diameter ratio (i.e. diameter of larger particle to smaller particle (d₁/d₂)) is varied from 2:1, 3:1 and 4:1. For each case of particle diameter ratio, solid volume fraction for each particle size (φ₁/φ₂) is varied from 1:1, 1:2 and 2:1. For comparison, simulations are also performed for monodisperse particles. For studying particles clustering, radial distribution function and instantaneous location of particles in the computational domain are studied. It is observed that the degree of particle clustering decreases with the increase in the bi-dispersity of settling particles. The smallest degree of particle clustering or dispersion of particles is observed for particles with d₁/d₂ equal to 4:1 and φ₁/φ₂ equal to 1:2. Simulations showed that the reduction in particle clustering by increasing bi-dispersity is due to the difference in settling velocity of particles. Particles with larger size settle faster and knockout the smaller particles from clustered regions of particles in the computational domain. <p class="card-text"><strong>Keywords:</strong> <a
