Therefore, the FDC is widely used for water resource projects such as hydropower, water supply, irrigation and water quality management. The primary purpose of this study is to obtain synthetic daily flow duration curves for Çoruh Basin, Turkey. For this aim, we firstly developed univariate auto-regressive moving average (ARMA) models for daily flows of 9 stations located in Çoruh basin and then these models were used to generate 100 synthetic flow series each having same size as historical series. Secondly, flow duration curves of each synthetic series were drawn and the flow values exceeded 10, 50 and 95 % of the time and 95% confidence limit of these flows were calculated. As a result, flood, mean and low flows potential of Çoruh basin will comprehensively be represented. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ARMA%20models" title="ARMA models">ARMA models</a>, <a href="https://publications.waset.org/abstracts/search?q=%C3%87oruh%20basin" title=" Çoruh basin"> Çoruh basin</a>, <a href="https://publications.waset.org/abstracts/search?q=flow%20duration%20curve" title=" flow duration curve"> flow duration curve</a>, <a href="https://publications.waset.org/abstracts/search?q=Turkey" title=" Turkey"> Turkey</a> </p> <a href="https://publications.waset.org/abstracts/31172/synthetic-daily-flow-duration-curves-for-the-coruh-river-basin-turkey" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/31172.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">404</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">7117</span> Pressure Gradient Prediction of Oil-Water Two Phase Flow through Horizontal Pipe</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20I.%20Raheem">Ahmed I.

The aim of our research is to develop an improved model of assessing a company’s development results. The model should take into account the cyclical nature of development and the high degree of uncertainty in dealing with numerous management tasks. Our hypotheses may be formulated as follows: Hypothesis 1. The cycle of a company’s development may be studied from the standpoint of a project cycle. To do that, methods and tools of project analysis are to be used. Hypothesis 2. The problem of the uncertainty when justifying managerial decisions within the framework of a company’s development cycle can be solved through the use of the mathematical apparatus of fuzzy logic. The reasoned justification of the validity of the hypotheses made is given in the suggested article. The fuzzy logic toolkit applies to the case of technology shift within an enterprise. It is proven that some restrictions in performance measurement that are incurred to conventional methods could be eliminated by implementation of the fuzzy logic apparatus in performance measurement models. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=logic" title="logic">logic</a>, <a href="https://publications.waset.org/abstracts/search?q=fuzzy%20sets" title=" fuzzy sets"> fuzzy sets</a>, <a href="https://publications.waset.org/abstracts/search?q=performance%20measurement" title=" performance measurement"> performance measurement</a>, <a href="https://publications.waset.org/abstracts/search?q=project%20analysis" title=" project analysis"> project analysis</a> </p> <a href="https://publications.waset.org/abstracts/40744/evolution-of-performance-measurement-methods-in-conditions-of-uncertainty-the-implementation-of-fuzzy-sets-in-performance-measurement" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/40744.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">381</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">7115</span> Gas-Liquid Flow Void Fraction Identification Using Slippage Number Froud Mixture Number Relation in Bubbly Flow</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jaber%20Masoud%20Alyami">Jaber Masoud Alyami</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdelsalam%20H.%20Alsrkhi"> Abdelsalam H.

Yet, the introduction of dimensionless numbers used to grasp gas-liquid flow is a significant step in controlling and improving the multi-phase flow area. SL (Slippage number), for instance is a strong dimensionless number defined as a the ratio of the difference in gravitational forces between slip and no-slip conditions to the inertial force of the gas. The fact that plotting SL versus Frm provides a single acceptable curve for all of the data provided proves that SL may be used to realize the behavior of gas-liquid flow. This paper creates a numerical link between SL and Froud mixing number using vertical gas-liquid flow and then utilizes that relationship to validate its reliability in practice. An improved correlation in drift flux model generated from the experimental data and its rationality has been verified. The method in this paper is to approach for predicting the void fraction in bubbly flow through SL/Frm relation and the limitations of this method, as well as areas for development, are stated. <p class="card-text"><strong>Keywords:</strong> <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%20flow" title=" gas-liquid flow"> gas-liquid flow</a>, <a href="https://publications.waset.org/abstracts/search?q=slippage" title=" slippage"> slippage</a>, <a href="https://publications.waset.org/abstracts/search?q=void%20farction" title=" void farction"> void farction</a> </p> <a href="https://publications.waset.org/abstracts/164960/gas-liquid-flow-void-fraction-identification-using-slippage-number-froud-mixture-number-relation-in-bubbly-flow" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/164960.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">85</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">7114</span> Lean Impact Analysis Assessment Models: Development of a Lean Measurement Structural Model</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Catherine%20Maware">Catherine Maware</a>, <a href="https://publications.waset.org/abstracts/search?q=Olufemi%20Adetunji"> Olufemi Adetunji</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The paper is aimed at developing a model to measure the impact of Lean manufacturing deployment on organizational performance. The model will help industry practitioners to assess the impact of implementing Lean constructs on organizational performance. It will also harmonize the measurement models of Lean performance with the house of Lean that seems to have become the industry standard. The sheer number of measurement models for impact assessment of Lean implementation makes it difficult for new adopters to select an appropriate assessment model or deployment methodology. A literature review is conducted to classify the Lean performance model. Pareto analysis is used to select the Lean constructs for the development of the model. The model is further formalized through the use of Structural Equation Modeling (SEM) in defining the underlying latent structure of a Lean system. An impact assessment measurement model developed can be used to measure Lean performance and can be adopted by different industries. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=impact%20measurement%20model" title="impact measurement model">impact measurement model</a>, <a href="https://publications.waset.org/abstracts/search?q=lean%20bundles" title=" lean bundles"> lean bundles</a>, <a href="https://publications.waset.org/abstracts/search?q=lean%20manufacturing" title=" lean manufacturing"> lean manufacturing</a>, <a href="https://publications.waset.org/abstracts/search?q=organizational%20performance" title=" organizational performance"> organizational performance</a> </p> <a href="https://publications.waset.org/abstracts/91848/lean-impact-analysis-assessment-models-development-of-a-lean-measurement-structural-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/91848.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">485</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">7113</span> A Monocular Measurement for 3D Objects Based on Distance Area Number and New Minimize Projection Error Optimization Algorithms</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Feixiang%20Zhao">Feixiang Zhao</a>, <a href="https://publications.waset.org/abstracts/search?q=Shuangcheng%20Jia"> Shuangcheng Jia</a>, <a href="https://publications.waset.org/abstracts/search?q=Qian%20Li"> Qian Li</a> </p> <p class="card-text"><strong>Abstract:</strong></p> High-precision measurement of the target’s position and size is one of the hotspots in the field of vision inspection. This paper proposes a three-dimensional object positioning and measurement method using a monocular camera and GPS, namely the Distance Area Number-New Minimize Projection Error (DAN-NMPE). Our algorithm contains two parts: DAN and NMPE; specifically, DAN is a picture sequence algorithm, NMPE is a relatively positive optimization algorithm, which greatly improves the measurement accuracy of the target’s position and size. Comprehensive experiments validate the effectiveness of our proposed method on a self-made traffic sign dataset. The results show that with the laser point cloud as the ground truth, the size and position errors of the traffic sign measured by this method are ± 5% and 0.48 ± 0.3m, respectively. In addition, we also compared it with the current mainstream method, which uses a monocular camera to locate and measure traffic signs. DAN-NMPE attains significant improvements compared to existing state-of-the-art methods, which improves the measurement accuracy of size and position by 50% and 15.8%, respectively. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=monocular%20camera" title="monocular camera">monocular camera</a>, <a href="https://publications.waset.org/abstracts/search?q=GPS" title=" GPS"> GPS</a>, <a href="https://publications.waset.org/abstracts/search?q=positioning" title=" positioning"> positioning</a>, <a href="https://publications.waset.org/abstracts/search?q=measurement" title=" measurement"> measurement</a> </p> <a href="https://publications.waset.org/abstracts/147790/a-monocular-measurement-for-3d-objects-based-on-distance-area-number-and-new-minimize-projection-error-optimization-algorithms" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/147790.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">144</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">7112</span> Magnetohydrodynamic Flow over an Exponentially Stretching Sheet</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Raj%20Nandkeolyar">Raj Nandkeolyar</a>, <a href="https://publications.waset.org/abstracts/search?q=Precious%20Sibanda"> Precious Sibanda</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The flow of a viscous, incompressible, and electrically conducting fluid under the influence of aligned magnetic field acting along the direction of fluid flow over an exponentially stretching sheet is investigated numerically.

The main manifestations are the randomness and discretization degree increasing of the tightening performance. To evaluate the degradation tendency of the tightening performance accurately, a complexity measurement approach based on Kolmogorov entropy is presented. At first, the states of performance index are divided for calibrating the discrete degree. Then the complexity measurement model based on Kolmogorov entropy is built. The model describes the performance degradation tendency of tightening equipment quantitatively. At last, a study case is applied for verifying the efficiency and validity of the approach. The research achievement shows that the presented complexity measurement can effectively evaluate the degradation tendency of the tightening equipment.

A mathematical model of a double flow solar air heater, in which air is flowing simultaneously over and under the absorbing plate is presented and solved by developing a computer program in C++ language. The performance evaluation is studied in terms of air temperature rise, energy, effective and exergy efficiencies. The performance of double flow corrugated absorber is compared with double flow flat plate and conventional solar air heaters. It is found that double flow effectively increases the air temperature rise and efficiencies in comparison to a conventional collector. However, corrugated absorber is more superior to that of flat plate double flow solar air heater. The results show that increasing the solar radiation leads to achieve higher air temperature rise and efficiencies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=corrugated%20absorber" title="corrugated absorber">corrugated absorber</a>, <a href="https://publications.waset.org/abstracts/search?q=double%20flow" title=" double flow"> double flow</a>, <a href="https://publications.waset.org/abstracts/search?q=flat%20plate" title=" flat plate"> flat plate</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20air%20heater" title=" solar air heater"> solar air heater</a> </p> <a href="https://publications.waset.org/abstracts/68855/analysis-of-the-effect-of-gsr-on-the-performance-of-double-flow-corrugated-absorber-solar-air-heater" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/68855.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">351</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">7108</span> Real Time Video Based Smoke Detection Using Double Optical Flow Estimation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anton%20Stadler">Anton Stadler</a>, <a href="https://publications.waset.org/abstracts/search?q=Thorsten%20Ike"> Thorsten Ike</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, we present a video based smoke detection algorithm based on TVL1 optical flow estimation.

Pulp fiber concentrations of the wake downstream of the plate were investigated by flow visualization and optical measurements. Changes in the time-averaged and fluctuation of the fiber concentration along the flow direction were examined. In addition, the control of the flow characteristics in the two channels was investigated. The behaviors of the pulp fibers and the wake flow were found to be strongly related to the flow states in the upstream passages partitioned by the plate. The distribution of the fiber concentration was complex because of the formation of a thin water layer on the plate and the generation of Karman’s vortices at the trailing edge of the plate. Compared with the flow in the parallel channel, fluctuations in the fiber concentration decreased in the convergent channel. However, at low flow velocities, the convergent channel has a weak effect on equilibrating the time-averaged fiber concentration. This shows that a rectangular trailing edge cannot adequately disperse pulp suspensions; thus, at low flow velocities, a convergent channel is ineffective in ensuring uniform fiber concentration. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fiber%20dispersion" title="fiber dispersion">fiber dispersion</a>, <a href="https://publications.waset.org/abstracts/search?q=headbox" title=" headbox"> headbox</a>, <a href="https://publications.waset.org/abstracts/search?q=pulp%20liquid" title=" pulp liquid"> pulp liquid</a>, <a href="https://publications.waset.org/abstracts/search?q=wake%20flow" title=" wake flow"> wake flow</a> </p> <a href="https://publications.waset.org/abstracts/62014/experimental-study-of-the-fiber-dispersion-of-pulp-liquid-flow-in-channels-with-application-to-papermaking" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/62014.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">386</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">7106</span> Influence of Internal Heat Source on Thermal Instability in a Horizontal Porous Layer with Mass Flow and Inclined Temperature Gradient</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Anjanna%20Matta">Anjanna Matta</a>, <a href="https://publications.waset.org/abstracts/search?q=P.%20A.%20L.%20Narayana"> P.

Water then enters stationary pitot-tube collector (diffuser), which discharges to the outside. By means of ANSYS Fluent 15.0, the internal flow characteristics for Pitot-tube Jet pump with standard pitot and curved pitot are studied. Under design condition, realizable k-e turbulence model and SIMPLEC algorithm are used to calculate 3D flow field inside both pumps. The simulation results reveal that energy is imparted to the flow by impeller and inside the rotor, forced vortex type flow is observed. Total pressure decreases inside pitot-tube whereas static pressure increases. Changing pitot-tube from standard to curved shape results in minimum flow circulation inside pitot-tube and leads to a higher pump performance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CFD" title="CFD">CFD</a>, <a href="https://publications.waset.org/abstracts/search?q=flow%20circulation" title=" flow circulation"> flow circulation</a>, <a href="https://publications.waset.org/abstracts/search?q=high%20pressure%20pump" title=" high pressure pump"> high pressure pump</a>, <a href="https://publications.waset.org/abstracts/search?q=impeller" title=" impeller"> impeller</a>, <a href="https://publications.waset.org/abstracts/search?q=internal%20flow" title=" internal flow"> internal flow</a>, <a href="https://publications.waset.org/abstracts/search?q=pickup%20tube%20pump" title=" pickup tube pump"> pickup tube pump</a>, <a href="https://publications.waset.org/abstracts/search?q=rectangle%20channels" title=" rectangle channels"> rectangle channels</a>, <a href="https://publications.waset.org/abstracts/search?q=rotating%20casing" title=" rotating casing"> rotating casing</a>, <a href="https://publications.waset.org/abstracts/search?q=turbulence" title=" turbulence"> turbulence</a> </p> <a href="https://publications.waset.org/abstracts/132118/simulation-of-internal-flow-field-of-pitot-tube-jet-pump" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/132118.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">7104</span> Comparison of Flow and Mixing Characteristics between Non-Oscillating and Transversely Oscillating Jet</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dinku%20Seyoum%20Zeleke">Dinku Seyoum Zeleke</a>, <a href="https://publications.waset.org/abstracts/search?q=Rong%20Fung%20Huang"> Rong Fung Huang</a>, <a href="https://publications.waset.org/abstracts/search?q=Ching%20Min%20Hsu"> Ching Min Hsu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Comparison of flow and mixing characteristics between non-oscillating jet and transversely oscillating jet was investigated experimentally. Flow evolution process was detected by using high-speed digital camera, and jet spread width was calculated using binary edge detection techniques by using the long-exposure images. The velocity characteristics of transversely oscillating jet induced by a V-shaped fluidic oscillator were measured using single component hot-wire anemometer. The jet spread width of non-oscillating jet was much smaller than the jet exit gap because of behaving natural jet behaviors. However, the transversely oscillating jet has a larger jet spread width, which was associated with the excitation of the flow by self-induced oscillation. As a result, the flow mixing characteristics desperately improved both near-field and far-field. Therefore, this transversely oscillating jet has a better turbulence intensity, entrainment, and spreading width so that it augments flow-mixing characteristics desperately. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=flow%20mixing" title="flow mixing">flow mixing</a>, <a href="https://publications.waset.org/abstracts/search?q=transversely%20oscillating" title=" transversely oscillating"> transversely oscillating</a>, <a href="https://publications.waset.org/abstracts/search?q=spreading%20width" title=" spreading width"> spreading width</a>, <a href="https://publications.waset.org/abstracts/search?q=velocity%20characteristics" title=" velocity characteristics"> velocity characteristics</a> </p> <a href="https://publications.waset.org/abstracts/124309/comparison-of-flow-and-mixing-characteristics-between-non-oscillating-and-transversely-oscillating-jet" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/124309.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">249</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">7103</span> High Viscous Oil–Water Flow: Experiments and CFD Simulations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Archibong-Eso">A.

Both subcritical and supercritical regimes are considered. Generally, when considering the theoretical problem of the free-surface flow, in a fluid domain of finite depth, due to the presence of an obstacle, we suppose that the water is an inviscid fluid, which means that there is no sheared velocity profile, but constant upstream. In a hydraulic channel, it is impossible to satisfy this condition. Indeed, water is a viscous fluid and its velocity is null at the bottom. The two configurations are presented, i.e. a flow over an obstacle and a towed obstacle in a resting fluid. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=experiments" title="experiments">experiments</a>, <a href="https://publications.waset.org/abstracts/search?q=free-surface%20flow" title=" free-surface flow"> free-surface flow</a>, <a href="https://publications.waset.org/abstracts/search?q=hydraulic%20channel" title=" hydraulic channel"> hydraulic channel</a>, <a href="https://publications.waset.org/abstracts/search?q=subcritical%20regime" title=" subcritical regime"> subcritical regime</a>, <a href="https://publications.waset.org/abstracts/search?q=supercritical%20flow" title=" supercritical flow"> supercritical flow</a> </p> <a href="https://publications.waset.org/abstracts/75299/on-the-free-surface-generated-by-the-flow-over-an-obstacle-in-a-hydraulic-channel" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/75299.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">307</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">7101</span> Heat Transfer from a Cylinder in Cross-Flow of Single and Multiphase Flows</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=F.%20A.%20Hamad">F.

He</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, the average heat transfer characteristics for a cross flow cylinder of 16 mm diameter in a vertical pipe has been studied for single-phase flow (water/oil) and multicomponent (non-boiling) flow (water-air, water-oil, oil-air and water-oil-air). The cylinder is uniformly heated by electrical heater placed at the centre of the element. The results show that the values of average heat transfer coefficients for water are around four times the values for oil flow. Introducing air as a second phase with water has very little effect on heat transfer rate, while the heat transfer increased by 70% in case of oil. For water–oil flow, the heat transfer coefficient values are reflecting the percentage of water up to 50%, but increasing the water more than 50% leads to a sharp increase in the heat transfer coefficients to become close to the values of pure water. The enhancement of heat transfer by mixing two phases may be attributed to the changes in flow structure near to cylinder surface which lead to thinner boundary layer and higher turbulence. For three-phase flow, the heat transfer coefficients for all cases fall within the limit of single-phase flow of water and oil and are very close to pure water values. The net effect of the turbulence augmentation due to the introduction of air and the attenuation due to the introduction of oil leads to a thinner boundary layer of oil over the cylinder surface covered by a mixture of water and air bubbles. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=circular%20cylinder" title="circular cylinder">circular cylinder</a>, <a href="https://publications.waset.org/abstracts/search?q=cross%20flow" title=" cross flow"> cross flow</a>, <a href="https://publications.waset.org/abstracts/search?q=hear%20transfer" title=" hear transfer"> hear transfer</a>, <a href="https://publications.waset.org/abstracts/search?q=multicomponent%20multiphase%20flow" title=" multicomponent multiphase flow"> multicomponent multiphase flow</a> </p> <a href="https://publications.waset.org/abstracts/55747/heat-transfer-from-a-cylinder-in-cross-flow-of-single-and-multiphase-flows" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/55747.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">397</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">7100</span> Thermohydraulic Performance of Double Flow Solar Air Heater with Corrugated Absorber</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20P.%20Sharma">S.

Some students find artistic self-expression and its related creative processes overwhelming. Low creative self-efficacy levels and creative habits of mind can impede their levels of motivation, engagement and persistence. For some, creative arts engagement can induce a state of anxiety and distress as opposed to flow. Flow theory posits that learners are happiest when they are learning in a state of flow. During the flow state, students feel, think and perform their best. They become so involved in the learning experience that nothing else seems to matter. The creative flow state is a crucial conduit of artistic processes to enable learners to explore and produce their best work. Despite the research conducted on flow state across several contexts, the phenomenon of personal flow state remains quite elusive. While some research has examined flow in relation to characteristics, conditions and personality traits, no research has investigated individuals' personal experiences of flow in a visual and tangible manner nor explored a relationship between flow state and teachers’ artistic development. This explorative case study explores preservice teachers’ impressions of flow using an arts-based approach. It identifies, categorizes and discusses patterns of commonality and difference. Grounded by theory concerning flow, self-efficacy and creative habits, this study ponders how emerging findings regarding flow impressions might aid teacher arts educators in helping preservice teachers who struggle with creative self-expression. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=creative%20arts" title="creative arts">creative arts</a>, <a href="https://publications.waset.org/abstracts/search?q=flow%20theory" title=" flow theory"> flow theory</a>, <a href="https://publications.waset.org/abstracts/search?q=presence" title=" presence"> presence</a>, <a href="https://publications.waset.org/abstracts/search?q=self-efficacy" title=" self-efficacy"> self-efficacy</a>, <a href="https://publications.waset.org/abstracts/search?q=teacher%20education" title=" teacher education"> teacher education</a> </p> <a href="https://publications.waset.org/abstracts/186944/combating-contraflow-to-creativity-amongst-preservice-teachers-in-teacher-arts-education" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/186944.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">28</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">7098</span> Unsteady Flow and Heat Transfer of Nanofluid from Circular Tube in Cross-Flow</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=H.%20Bayat">H.

The governing equations are solved by using finite volume method. Reynolds number varies in range of 50 to 200, in this range flow is considered to be laminar and unsteady. Al2O3 nanoparticle with volume fraction in range of 5% to 20% is added to pure water. Effects of adding nanoparticle to pure water on lift and drag coefficient and Nusselt number is presented. Addition of Al2O3 has inconsiderable effect on the value of drags and lift coefficient. However, it has significant effect on heat transfer; results show that heat transfer of Al2O3 nanofluid is about 9% to 36% higher than pure water. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nanofluid" title="nanofluid">nanofluid</a>, <a href="https://publications.waset.org/abstracts/search?q=heat%20transfer" title=" heat transfer"> heat transfer</a>, <a href="https://publications.waset.org/abstracts/search?q=unsteady%20flow" title=" unsteady flow"> unsteady flow</a>, <a href="https://publications.waset.org/abstracts/search?q=forced%20convection" title=" forced convection"> forced convection</a>, <a href="https://publications.waset.org/abstracts/search?q=cross-flow" title=" cross-flow"> cross-flow</a> </p> <a href="https://publications.waset.org/abstracts/42064/unsteady-flow-and-heat-transfer-of-nanofluid-from-circular-tube-in-cross-flow" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42064.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">397</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">7097</span> Measurement and Evaluation Patterns Practiced by Physical Education Teachers in North Badia in Jordan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aman%20Kasawneh">Aman Kasawneh</a>, <a href="https://publications.waset.org/abstracts/search?q=Wasfi%20Khazalah"> Wasfi Khazalah</a>, <a href="https://publications.waset.org/abstracts/search?q=Abedalbasit%20Abedalhafiz"> Abedalbasit Abedalhafiz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study aimed to identify the patterns of measurement and evaluation practiced by physical education in the schools of North Badia in Jordan, as well as identifying the statistical differences according to gender, educational qualification, and the experience.

The incompressible Poisson-Nernst-Plank equations and the Navier-Stokes equations are approximated by lubrication theory to quantify the flow structure due to hydrophobic and hydrophilic surfaces. The analytical quantification of velocity and pressure of electroosmotic flow (EOF) is made with the numerical results due to the staggered grid based finite volume method for flow governing equations. The resistance force due to fluid friction and shear force along the surface are decreased by the hydrophobicity, enables the faster movement of fluid particles. The resulting flow enhancement factor Ef is increased with the low viscous fluid and provides maximum species transport. Also, the analytical comparison of EOF with pressure driven EOF justifies the flow enhancement due to hydrophobicity and shear impact on flow variation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electroosmotic%20flow" title="electroosmotic flow">electroosmotic flow</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrophobic%20surface" title=" hydrophobic surface"> hydrophobic surface</a>, <a href="https://publications.waset.org/abstracts/search?q=power-law%20fluid" title=" power-law fluid"> power-law fluid</a>, <a href="https://publications.waset.org/abstracts/search?q=shear%20effect" title=" shear effect"> shear effect</a> </p> <a href="https://publications.waset.org/abstracts/81689/electrokinetic-transport-of-power-law-fluid-through-hydrophobic-micro-slits" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/81689.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">377</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">7095</span> Energy Separation Mechanism in Uni-Flow Vortex Tube Using Compressible Vortex Flow </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hiroshi%20Katanoda">Hiroshi Katanoda</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohd%20Hazwan%20bin%20Yusof"> Mohd Hazwan bin Yusof</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A theoretical investigation from the viewpoint of gas-dynamics and thermodynamics was carried out, in order to clarify the energy separation mechanism in a viscous compressible vortex, as a primary flow element in a uni-flow vortex tube.

The major goal is to investigate the influence of inertial flow owing to fracture wall roughness on nonlinear flow behavior. Roughness profiles are developed using Barton's Joint Roughness Coefficient (JRC) and used as fracture walls to assess wall roughness. Four JRC profiles (5, 11, 15, and 19) are employed in the study, where a higher number indicates higher roughness. A parametric study has been performed using varying pressure gradients, and the corresponding Forchheimer number is calculated to observe the nonlinear behavior. The results indicate that the fracture roughness has a significant effect on the onset of nonlinearity. Additionally, the validity of the cubic law is evaluated and observed that it overestimates the flow in rough fractures and should be used with utmost care. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fracture%20flow" title="fracture flow">fracture flow</a>, <a href="https://publications.waset.org/abstracts/search?q=nonlinear%20flow" title=" nonlinear flow"> nonlinear flow</a>, <a href="https://publications.waset.org/abstracts/search?q=cubic%20law" title=" cubic law"> cubic law</a>, <a href="https://publications.waset.org/abstracts/search?q=Navier-stokes%20equation" title=" Navier-stokes equation"> Navier-stokes equation</a> </p> <a href="https://publications.waset.org/abstracts/149916/nonlinear-flow-behavior-and-validity-of-the-cubic-law-in-a-rough-fracture" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/149916.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">109</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">7090</span> Numerical Analysis of the Flow Characteristics Around a Deformable Vortex Generator</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aimad%20Koulali">Aimad Koulali</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Flow structure evolution around a single pair of Delta vortex generators (VGs) is studied numerically.

The flow over delta wings can be characterized by a pair of leading edge vortices emanating from wing apex. Boundary layer separation causes these vortical structures formed by rolling up of viscous flow sheet. This flow separation mechanism is occurred due to angle of attack and sharp leading edges of the delta wing. Therefore, complexity and variety in planform designs rise to catch the best under abnormal flow conditions. The present experimental study investigates the near surface flow structure and aerodynamic flow characteristics of X-45 type non-slender delta wing planform using dye visualization, Stereoscopic Particle Image Velocimetry (stereo-PIV). The instantaneous images are acquired on the plan-view plane within 5o≤α≤20o to calculate the time-averaged flow data. It can be concluded that vortical flow with a pair of well-defined LEVs over X-45 develop at very low angles of attack, secondary vortex are also evident and form close to the wing surface similar to delta and lambda planforms. The stall occurs at an angle of attack α=32o. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aerodynamic"
