crucial problem for the dynamic of moving containers in the packaging industries. Sloshing issues have been so far mainly modeled within the framework of fluid dynamics or by using equivalent mechanical models with different kinds of movements and shapes of containers. Nevertheless, these approaches do not allow to determinate the shape of the free surface of the liquid in case of the irregular shape of the moving containers, so that experimental measurements may be required. If there is too much slosh in the moving tank, the liquid can be splashed out on the packages. So, the free surface oscillation must be controlled/reduced to eliminate the splashing. The purpose of this research is to propose an optimization algorithm for finding an optimum command law to reduce surface elevation. In the first step, the free surface of the liquid is simulated based on the separation variable and weak formulation models. Then Genetic and Gradient algorithms are developed for finding the optimum command law. The optimum command law is compared with existing command laws, and the results show that there is a significant difference in surface oscillation between optimum and existing command laws. This algorithm is applicable for different varieties of bottles in case of using the camera for detecting the liquid elevation, and it can produce new command laws for different kinds of tanks to reduce the surface oscillation and remove the splashing phenomenon. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sloshing%20phenomenon" title="sloshing phenomenon">sloshing phenomenon</a>, <a href="https://publications.waset.org/abstracts/search?q=separation%20variables" title=" separation variables"> separation variables</a>, <a href="https://publications.waset.org/abstracts/search?q=weak%20formulation" title=" weak formulation"> weak formulation</a>, <a href="https://publications.waset.org/abstracts/search?q=optimization%20algorithm" title=" optimization algorithm"> optimization algorithm</a>, <a href="https://publications.waset.org/abstracts/search?q=command%20law" title=" command law"> command law</a> </p> <a href="https://publications.waset.org/abstracts/124624/an-optimization-algorithm-for-reducing-the-liquid-oscillation-in-the-moving-containers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/124624.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">151</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">2747</span> Sloshing Response of Liquid in Prismatic Container under Oscillation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=P.%20R.%20Maiti">P.

Determination of sloshing frequency in container is important to avoid resonance condition of the system. The complex behavior of the free surface movement and its combined mode of vibration make difficulty for exact analysis of sloshing. In the present study, numerical analysis is carried out for a partially liquid filled tank under external forces.

Analysis of liquid containing tanks is known to be complex due to hydrodynamic force exerted on tank which makes the analysis a complex one. The objective of this research is to carry out analysis of liquid domain along with structural interaction for various geometries of circular tanks considering seismic effects. An attempt has been made to determine hydrodynamic pressure distribution on the tank wall considering impulsive and convective components of liquid mass. To get a better picture, a comparative study of Draft IS 1893 Part 2, ACI 350.3 and Eurocode 8 for Circular Shaped Tank has been performed. Further, the differences in the magnitude of shear and moment at base as obtained from static (IS 3370 IV) and dynamic (Draft IS 1892 Part 2) analysis of ground supported circular tank highlight the need for us to mature from the old code to a newer code, which is more accurate and reliable. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=liquid%20filled%20containers" title="liquid filled containers">liquid filled containers</a>, <a href="https://publications.waset.org/abstracts/search?q=circular%20tanks" title=" circular tanks"> circular tanks</a>, <a href="https://publications.waset.org/abstracts/search?q=IS%201893%20%28part%202%29" title=" IS 1893 (part 2)"> IS 1893 (part 2)</a>, <a href="https://publications.waset.org/abstracts/search?q=seismic%20analysis" title=" seismic analysis"> seismic analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=sloshing" title=" sloshing"> sloshing</a> </p> <a href="https://publications.waset.org/abstracts/28169/comparative-study-of-dynamic-effect-on-analysis-approaches-for-circular-tanks-using-codal-provisions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/28169.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">2745</span> Effect of Testing Device Calibration on Liquid Limit Assessment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20O.%20Bayram">M.

The two methods majorly diverge from each other in terms of operator dependency. The Casagrande method that is applied according to ASTM D4318-17 standards may give misleading results, especially if the calibration process is not performed well. To reveal the effect of calibration for drop height and amount of soil paste placement in the Casagrande cup, a series of tests were carried out by multipoint method as it is specified in the ASTM standards. The tests include the combination of 6 mm, 8 mm, 10 mm, and 12 mm drop heights and under-filled, half-filled, and full-filled Casagrande cups by kaolinite samples. It was observed that during successive tests, the drop height of the cup deteriorated; hence the device was recalibrated before and after each test to provide the accuracy of the results. Besides, the tests by under-filled and full-filled samples for higher drop heights revealed lower liquid limit values than the lower drop heights revealed. For the half-filled samples, it was clearly seen that the liquid limit values didn’t change at all as the drop height increased, and this explains the function of standard specifications. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=calibration" title="calibration">calibration</a>, <a href="https://publications.waset.org/abstracts/search?q=casagrande%20cup%20method" title=" casagrande cup method"> casagrande cup method</a>, <a href="https://publications.waset.org/abstracts/search?q=drop%20height" title=" drop height"> drop height</a>, <a href="https://publications.waset.org/abstracts/search?q=kaolinite" title=" kaolinite"> kaolinite</a>, <a href="https://publications.waset.org/abstracts/search?q=liquid%20limit" title=" liquid limit"> liquid limit</a>, <a href="https://publications.waset.org/abstracts/search?q=placing%20form" title=" placing form"> placing form</a> </p> <a href="https://publications.waset.org/abstracts/151571/effect-of-testing-device-calibration-on-liquid-limit-assessment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/151571.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">2744</span> Evaluation of Sloshing in Process Equipment for Floating Cryogenic Application </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bo%20Jin">Bo Jin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A variety of process equipment having flow in and out is widely used in industrial land-based cryogenic facilities. In some of this equipment, such as vapor-liquid separator, a liquid level is established during the steady operation. As the implementation of such industrial processes extends to off-shore floating facilities, it is important to investigate the effect of sea motion on the process equipment partially filled with liquid. One important aspect to consider is the occurrence of sloshing therein. The flow characteristics are different from the classical study of sloshing, where the fluid is enclosed inside a vessel (e.g., storage tank) with no flow in or out. Liquid inside process equipment continuously flows in and out of the system. To understand this key difference, a Computational Fluid Dynamics (CFD) model is developed to simulate the liquid motion inside a partially filled cylinder with and without continuous flow in and out. For a partially filled vertical cylinder without any continuous flow in and out, the CFD model is found to be able to capture the well-known sloshing behavior documented in the literature. For the cylinder with a continuous steady flow in and out, the CFD simulation results demonstrate that the continuous flow suppresses sloshing. Given typical cryogenic fluid has very low viscosity, an analysis based on potential flow theory is developed to explain why flow into and out of the cylinder changes the natural frequency of the system and thereby suppresses sloshing. This analysis further validates the CFD results. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=computational%20fluid%20dynamics" title="computational fluid dynamics">computational fluid dynamics</a>, <a href="https://publications.waset.org/abstracts/search?q=CFD" title=" CFD"> CFD</a>, <a href="https://publications.waset.org/abstracts/search?q=cryogenic%20process%20equipment" title=" cryogenic process equipment"> cryogenic process equipment</a>, <a href="https://publications.waset.org/abstracts/search?q=off-shore%20floating%20processes" title=" off-shore floating processes"> off-shore floating processes</a>, <a href="https://publications.waset.org/abstracts/search?q=sloshing" title=" sloshing "> sloshing </a> </p> <a href="https://publications.waset.org/abstracts/127327/evaluation-of-sloshing-in-process-equipment-for-floating-cryogenic-application" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/127327.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">137</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">2743</span> Study the Sloshing Phenomenon in the Tank Filled Partially with Liquid Using Computational Fluid Dynamics (CFD) Simulation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amit%20Kumar">Amit Kumar</a>, <a href="https://publications.waset.org/abstracts/search?q=Jaikumar%20V"> Jaikumar V</a>, <a href="https://publications.waset.org/abstracts/search?q=Pradeep%20AG"> Pradeep AG</a>, <a href="https://publications.waset.org/abstracts/search?q=Shivakumar%20%20Bhavi"> Shivakumar Bhavi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Reducing sloshing is one of the major challenges in industries where transporting of liquid involved.

Rheological parameters of liquid are temperature-sensitive, which ultimately results in a temperature dependence of the wave speed and attenuation in the waveguide. The study is devoted to modeling of this effect at sound propagation in an elastic pipe with polymeric liquid, described by generalized Maxwell model with non-zero high-frequency viscosity. It is assumed that relaxation spectrum is distributed according to the Spriggs law; temperature impact on the liquid rheology is described on the basis of the temperature-superposition principle and activation theory. The dispersion equation for the waveguide, considered as a thin-walled tube with polymeric solution, is obtained within a quasi-one-dimensional formulation.

As these materials are characterized by low thermal conductivity, it is necessary to develop heat transfer techniques to improve their thermophysical properties. This scientific article focuses on the geometrical configurations of encapsulated PCM containers and the impact of designs to improve the performance of the solar thermal cooling system. The literature review showed that in-depth research is being conducted on different methods of improving the efficiency of PCM heat transfer, which is the main design task for the containers. Techniques such as microencapsulated PCMs, adding fins and different combinations of fins and nanoparticles are used. The use of graphite, metal foam and doping of high photothermal materials is also being studied. To determine most efficient container configuration, the article looks at different designs of PCM containers with fins for the storage tank. This paper experimentally investigates the effect of the encapsulation design on the performance of a lab-scale thermal energy storage tank. The development of optimized energy storage with integrated phase change material containers reduces auxiliary heater energy consumption, increases the COP of the solar cooling system, and reduces the environmental impact of the cooling system. The review shows that in the cylindrical construction, the ratio between the radius of shell and tube is significant, which means this ratio is the main issue to enhance transfer efficiency and to increase the value of stored heat. Therefore, three cylindrical tube containers with different radiuses 20mm, 35mm, 50mm filled with commercial phase change material were tested. The results show that using a smaller radius achieved a higher power, leading to a reduction in the charging and discharging time. The three fins were added to the selected cylindrical tube to determine their effects on heat exchanging efficiency. The observed optimized performance given by the fin’s arrangement achieved a 40% reduction of PCM's melting time compared to the heat exchanging without fins. The exact dimensions of the PCM containers and fins placements will be presented on-site. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=energy%20performance" title="energy performance">energy performance</a>, <a href="https://publications.waset.org/abstracts/search?q=PCM%20containers" title=" PCM containers"> PCM containers</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20thermal%20cooling" title=" solar thermal cooling"> solar thermal cooling</a>, <a href="https://publications.waset.org/abstracts/search?q=storage%20tank" title=" storage tank"> storage tank</a> </p> <a href="https://publications.waset.org/abstracts/146483/performance-improvement-of-solar-thermal-cooling-systems-integrated-with-encapsulated-pcm" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/146483.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">140</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">2740</span> Vibration Mitigation in Partially Liquid-Filled Vessel Using Passive Energy Absorbers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maor%20Farid">Maor Farid</a>, <a href="https://publications.waset.org/abstracts/search?q=Oleg%20Gendelman"> Oleg Gendelman</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The following study deals with fluid vibration of a liquid in a partially filled vessel under periodic ground excitation. This external excitation might lead to hidraulic impact applied on the vessel inner walls. In order to model these sloshing dynamic regimes, several equivalent mechanical models were suggested in the literature, such as series of pendula or mass-spring systems that are able to impact the inner tank walls. In the following study, we use the latter methodology, use parameter values documented in literature corresponding to cylindrical tanks and consider structural elasticity of the tank. The hydraulic impulses are modeled by the high-exponent potential function. Additional system parameters are found with the help of Finite-Element (FE) analysis. Model-driven stress assessment method is developed.

When the storage tanks are partially filled, it is essential to be able to evaluate the fluid dynamic loads on the tank’s perimeter. In this paper, a numerical code was developed to determine the pressure distribution on the rectangular and trapezoidal storage tanks’ perimeters due to liquid sloshing impact. Assuming the fluid to be inviscid, the Laplace equation and the nonlinear free surface boundary conditions are solved using coupled BEM-FEM. The code performance for sloshing modeling is validated against available data. Finally, this code is used for partially filled rectangular and trapezoidal storage tanks and the pressure distribution on the tanks’ perimeters due to liquid sloshing impact is estimated. The results show that the maximum pressure on the perimeter of the rectangular and trapezoidal storage tanks was decreased along the sidewalls from the top to the bottom. Furthermore, the period of the pressure distribution is different for different points on the tank’s perimeter and it is bigger in the trapezoidal tanks compared to the rectangular ones. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pressure%20distribution" title="pressure distribution">pressure distribution</a>, <a href="https://publications.waset.org/abstracts/search?q=liquid%20sloshing%20impact" title=" liquid sloshing impact"> liquid sloshing impact</a>, <a href="https://publications.waset.org/abstracts/search?q=sway%20motion" title=" sway motion"> sway motion</a>, <a href="https://publications.waset.org/abstracts/search?q=trapezoidal%20storage%20tank" title=" trapezoidal storage tank"> trapezoidal storage tank</a>, <a href="https://publications.waset.org/abstracts/search?q=coupled%20BEM-FEM" title=" coupled BEM-FEM"> coupled BEM-FEM</a> </p> <a href="https://publications.waset.org/abstracts/20717/the-pressure-distribution-on-the-rectangular-and-trapezoidal-storage-tanks-perimeters-due-to-liquid-sloshing-impact" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/20717.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">551</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">2738</span> The Virtual Container Yard: Identifying the Persuasive Factors in Container Interchange</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=L.%20Edirisinghe">L.

It causes substantial cost to carriers, which inadvertently adds to the prices of consumer goods. The virtual container yard is rooted in the fundamentals of container interchange between carriers. If carriers opt to interchange their excess containers with those who are deficit, a substantial part of the empty reposition cost could be eliminated. Unlike in other types of ships, cargo cannot be directly loaded to a container ship. Slots and containers are supplementary components; thus, without containers, a carrier cannot ship cargo if the containers are not available and vice versa. Few decades ago, carriers recognized slot (the unit of space in a container ship) interchange as a viable solution for the imbalance of shipping space. Carriers interchange slots among them and it also increases the advantage of scale of economies in container shipping. Some of these service agreements between mega carriers have provisions to interchange containers too. However, the interchange mechanism is still not popular among carriers for containers. This is the paradox that prevails in the liner shipping industry. At present, carriers reposition their excess empty containers to areas where they are in demand. This research applied factor analysis statistical method. The paper reveals that five major components may influence the virtual container yard namely organisation, practice and culture, legal and environment, international nature, and marketing. There are 12 variables that may impact the virtual container yard, and these are explained in the paper. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=virtual%20container%20yard" title="virtual container yard">virtual container yard</a>, <a href="https://publications.waset.org/abstracts/search?q=shipping" title=" shipping"> shipping</a>, <a href="https://publications.waset.org/abstracts/search?q=imbalance" title=" imbalance"> imbalance</a>, <a href="https://publications.waset.org/abstracts/search?q=management" title=" management"> management</a>, <a href="https://publications.waset.org/abstracts/search?q=inventory" title=" inventory"> inventory</a> </p> <a href="https://publications.waset.org/abstracts/97126/the-virtual-container-yard-identifying-the-persuasive-factors-in-container-interchange" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/97126.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">196</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">2737</span> Study the Sloshing Phenomenon in the Tank Filled Partially with Liquid Using Computational Fluid Dynamics (CFD) Simulation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amit%20Kumar">Amit Kumar</a>, <a href="https://publications.waset.org/abstracts/search?q=Jaikumar%20V."> Jaikumar V.</a>, <a href="https://publications.waset.org/abstracts/search?q=Pradeep%20A.%20G."> Pradeep A.

Wang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The mixing process of two liquid layers in a cylindrical container includes the upper liquid with higher density rushing into the lower liquid with lighter density, the lower liquid rising into the upper liquid, meanwhile the two liquid layers having interactions with each other, forming vortices, spreading or dispersing in others, entraining or mixing with others. It is a complex process constituted of flow instability, turbulent mixing and other multiscale physical phenomena and having a fast evolution velocity. In order to explore the mechanism of the process and make further investigations, some experiments about the interfacial instability and mixing behavior between two liquid layers bounded in different volumes are carried out, applying the planar laser induced fluorescence (PLIF) and the high speed camera (HSC) techniques. According to the results, the evolution of interfacial instability between immiscible liquid develops faster than theoretical rate given by the Rayleigh-Taylor Instability (RTI) theory. It is reasonable to conjecture that some mechanisms except the RTI play key roles in the mixture process of two liquid layers. From the results, it is shown that the invading velocity of the upper liquid into the lower liquid does not depend on the upper liquid's volume (height). Comparing to the cases that the upper and lower containers are of identical diameter, in the case that the lower liquid volume increases to larger geometric space, the upper liquid spreads and expands into the lower liquid more quickly during the evolution of interfacial instability, indicating that the container wall has important influence on the mixing process. In the experiments of miscible liquid layers’ mixing, the diffusion time and pattern of the liquid interfacial mixing also does not depend on the upper liquid's volumes, and when the lower liquid volume increases to larger geometric space, the action of the bounded wall on the liquid falling and rising flow will decrease, and the liquid interfacial mixing effects will also attenuate. Therefore, it is also concluded that the volume weight of upper heavier liquid is not the reason of the fast interfacial instability evolution between the two liquid layers and the bounded wall action is limited to the unstable and mixing flow. The numerical simulations of the immiscible liquid layers’ interfacial instability flow using the VOF method show the typical flow pattern agree with the experiments. However the calculated instability development is much slower than the experimental measurement. The numerical simulation of the miscible liquids’ mixing, which applying Fick’s diffusion law to the components’ transport equation, shows a much faster mixing rate than the experiments on the liquids’ interface at the initial stage. It can be presumed that the interfacial tension plays an important role in the interfacial instability between the two liquid layers bounded in finite volume. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=interfacial%20instability%20and%20mixing" title="interfacial instability and mixing">interfacial instability and mixing</a>, <a href="https://publications.waset.org/abstracts/search?q=two%20liquid%20layers" title=" two liquid layers"> two liquid layers</a>, <a href="https://publications.waset.org/abstracts/search?q=Planar%20Laser%20Induced%20Fluorescence%20%28PLIF%29" title=" Planar Laser Induced Fluorescence (PLIF)"> Planar Laser Induced Fluorescence (PLIF)</a>, <a href="https://publications.waset.org/abstracts/search?q=High%20Speed%20Camera%20%28HSC%29" title=" High Speed Camera (HSC)"> High Speed Camera (HSC)</a>, <a href="https://publications.waset.org/abstracts/search?q=interfacial%20energy%20and%20tension" title=" interfacial energy and tension"> interfacial energy and tension</a>, <a href="https://publications.waset.org/abstracts/search?q=Cahn-Hilliard%20Navier-Stokes%20%28CHNS%29%20equations" title=" Cahn-Hilliard Navier-Stokes (CHNS) equations"> Cahn-Hilliard Navier-Stokes (CHNS) equations</a> </p> <a href="https://publications.waset.org/abstracts/68285/interfacial-instability-and-mixing-behavior-between-two-liquid-layers-bounded-in-finite-volumes" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/68285.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">248</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">2734</span> Terminal Ballistic Analysis of Non-Filled and Water-Filled Tank</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20R.%20Aziz">M.

The device is based on Tunable Diode Laser Absorption Spectroscopy (TDLAS) with a Wavelength Modulation Spectroscopy (WMS) technique in order to accomplish a non-invasive measurement inside closed containers of fermented dairy products (yogurts and fermented cheese in cups and bottles). The purpose of this instrument is the continuous monitoring of carbon dioxide concentration during incubation and storage of products over a time span of the whole shelf life of the product, in the presence of different microorganisms. The instrument’s optical front end has been designed to be integrated in a thermally stabilized incubator. An embedded computer provides processing of spectral artifacts and storage of an arbitrary set of calibration data allowing a properly calibrated measurement on many samples (cups and bottles) of different shapes and sizes commonly found in the retail distribution. A calibration protocol has been developed in order to be able to calibrate the instrument on the field also on containers which are notoriously difficult to seal properly. This calibration protocol is described and evaluated against reference measurements obtained through an industry standard (sampling) carbon dioxide metering technique. Some sets of validation test measurements on different containers are reported. Two test recordings of carbon dioxide concentration evolution are shown as an example of instrument operation. The first demonstrates the ability to monitor a rapid yeast growth in a contaminated sample through the increase of headspace carbon dioxide. Another experiment shows the dissolution transient with a non-saturated liquid medium in presence of a carbon dioxide rich headspace atmosphere. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=TDLAS" title="TDLAS">TDLAS</a>, <a href="https://publications.waset.org/abstracts/search?q=carbon%20dioxide" title=" carbon dioxide"> carbon dioxide</a>, <a href="https://publications.waset.org/abstracts/search?q=cups" title=" cups"> cups</a>, <a href="https://publications.waset.org/abstracts/search?q=headspace" title=" headspace"> headspace</a>, <a href="https://publications.waset.org/abstracts/search?q=measurement" title=" measurement"> measurement</a> </p> <a href="https://publications.waset.org/abstracts/41645/development-and-validation-of-a-carbon-dioxide-tdlas-sensor-for-studies-on-fermented-dairy-products" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41645.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">324</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">2731</span> A Simulation Study on the Applicability of Overbooking Strategies in Inland Container Transport</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20Fazi">S.

Similarly to other industries, overbooking could potentially limit these drawbacks at the cost of a lower service level in case of actual excess of capacity in overbooked rides. However, the presence of multiple modalities may provide the required flexibility in rescheduling and limit the dissatisfaction of the shippers in case of containers in overbooking. This flexibility is known with the term 'synchromodality'. In this paper, we evaluate via discrete event simulation the application of overbooking. Results show that in certain conditions overbooking can significantly increase profit and utilization of high-capacity means of transport, such as barges and trains. On the other hand, in case of high penalty costs and limited no-show, overbooking may lead to an excessive use of expensive trucks. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=discrete%20event%20simulation" title="discrete event simulation">discrete event simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=flexibility" title=" flexibility"> flexibility</a>, <a href="https://publications.waset.org/abstracts/search?q=inland%20shipping" title=" inland shipping"> inland shipping</a>, <a href="https://publications.waset.org/abstracts/search?q=multimodality" title=" multimodality"> multimodality</a>, <a href="https://publications.waset.org/abstracts/search?q=overbooking" title=" overbooking"> overbooking</a> </p> <a href="https://publications.waset.org/abstracts/117344/a-simulation-study-on-the-applicability-of-overbooking-strategies-in-inland-container-transport" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/117344.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">134</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">2730</span> Numerical Simulation and Analysis on Liquid Nitrogen Spray Heat Exchanger</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Wenjing%20Ding">Wenjing Ding</a>, <a href="https://publications.waset.org/abstracts/search?q=Weiwei%20Shan"> Weiwei Shan</a>, <a href="https://publications.waset.org/abstracts/search?q=Zijuan"> Zijuan</a>, <a href="https://publications.waset.org/abstracts/search?q=Wang"> Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Chao%20He"> Chao He</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Liquid spray heat exchanger is the critical equipment of temperature regulating system by gaseous nitrogen which realizes the environment temperature in the range of -180 ℃~+180 ℃.

By adjusting the pressure of liquid nitrogen and gaseous nitrogen, the flowrate of liquid nitrogen is changed to realize the required outlet temperature of heat exchanger. The temperature accuracy of shrouds is ±1 ℃. Liquid nitrogen spray heat exchanger is simulated by CATIA, and the numerical simulation is performed by FLUENT.

Containers arrive over time at the (importer) consignee, while the demand for containers arises from the (exporter) shipper. A match can be operated between an empty container from the consignee and the load from the shipper. Therefore, we model the system as a double-ended queue with non-zero matching time and a limited number of resources in order to optimize the reposition- ing decisions. We determine the performance measures when the consignee operates using a fixed withholding threshold policy. We show that the matching time mainly plays a role in the matching proportion, while under a certain duration, it only marginally impacts the consignee’s inventory policy and cost per container. Also, the withholding level is mainly determined by the shipper’s production rate. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=container" title="container">container</a>, <a href="https://publications.waset.org/abstracts/search?q=double-ended%20queue" title=" double-ended queue"> double-ended queue</a>, <a href="https://publications.waset.org/abstracts/search?q=inventory" title=" inventory"> inventory</a>, <a href="https://publications.waset.org/abstracts/search?q=Markov%20decision%20process" title=" Markov decision process"> Markov decision process</a>, <a href="https://publications.waset.org/abstracts/search?q=non-zero%20matching%20time" title=" non-zero matching time"> non-zero matching time</a>, <a href="https://publications.waset.org/abstracts/search?q=street-turn" title=" street-turn"> street-turn</a> </p> <a href="https://publications.waset.org/abstracts/159800/management-of-empty-containers-by-consignees-in-the-hinterland" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/159800.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">2726</span> Workers’ Prevention from Occupational Chemical Exposures during Container Handling</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bal%C3%A1zs%20%C3%81d%C3%A1m">Balázs Ádám</a>, <a href="https://publications.waset.org/abstracts/search?q=Randi%20N%C3%B8rgaard%20Fl%C3%B8e%20Pedersen"> Randi Nørgaard Fløe Pedersen</a>, <a href="https://publications.waset.org/abstracts/search?q=J%C3%B8rgen%20Riis%20Jepsen"> Jørgen Riis Jepsen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Volatile chemicals that accumulate and release from freight containers constitute significant health risks. Fumigation to prevent spread of pests and off-gassing of freight are sources of hazardous chemicals. The aim of our study was to investigate the regulation and practice of container handling with focus on preventive measures applied against chemical exposures in Denmark. A comprehensive systematic search of scientific literature and organizational domains of international and Danish regulatory bodies was performed to explore regulations related to safe work with transport containers. The practice of container work was investigated in a series of semi-structured interviews with managers and health and safety representatives of organizations that handle transport containers. Although there are several international and national regulations and local safety instructions that relate to container handling, the provided information is not specific or up-to-date enough to conduct safe practice in many aspects. The interviewees estimate high frequency of containers with chemical exposure and deem that they can potentially damage health, although recognizable health effects are rare. Knowledge is limited about the chemicals and most of them cannot be measured by available devices. Typical preventive measures are passive ventilation and personal protective equipment but their use is not consistent and may not provide adequate protection. Hazardous chemicals are frequently present in transport containers; however, managers, workers and even occupational health professionals have limited knowledge about the problem. Detailed risk assessment and specific instructions on risk management are needed to provide safe conditions for work with containers. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=chemical%20exposure" title="chemical exposure">chemical exposure</a>, <a href="https://publications.waset.org/abstracts/search?q=fumigation" title=" fumigation"> fumigation</a>, <a href="https://publications.waset.org/abstracts/search?q=occupational%20health%20and%20safety%20regulation" title=" occupational health and safety regulation"> occupational health and safety regulation</a>, <a href="https://publications.waset.org/abstracts/search?q=transport%20container" title=" transport container"> transport container</a> </p> <a href="https://publications.waset.org/abstracts/17882/workers-prevention-from-occupational-chemical-exposures-during-container-handling" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17882.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">2725</span> Basic Examination of Easily Distinguishable Tactile Symbols Attached to Containers and Packaging</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=T.%20Nishimura">T.

In particular, there is an urgent need to enhance information support for visually impaired persons who have difficulty accessing information. Recently, tactile symbols have been attached to various surfaces, such as the content labels of containers and packaging of various everyday products. The advantage of tactile symbols is that they are useful for visually impaired persons who cannot read Braille. The method of displaying tactile symbols is prescribed by the International Organization for Standardization (ISO). However, the quantitative data on the shapes and dimensions of tactile symbols is insufficient. In this study, through an evaluation experiments, we examine the easy-to-distinguish shapes and dimensions of tactile symbols used for various applications, including the content labels on containers and packaging. Visually impaired persons participated in the experiments. They used tactile symbols on a daily basis. The details and processes of the experiments were orally explained to the participants prior to the experiments, and the informed consent of the participants was obtained. They were instructed to touch the test pieces of tactile symbols freely with both hands. These tactile symbols were selected because they were likely to be easily distinguishable symbols on the content labels of top surfaces of containers and packaging based on a hearing survey that involved employees of an organization of visually impaired and a social welfare corporation, as well as academic experts of support technology for visually impaired. The participants then answered questions related to ease of distinguishing of tactile symbols on a scale of 5 (where 1 corresponded to ‘difficult to distinguish’ and 5 corresponded to ‘easy to distinguish’). Hearing surveys were also performed in an oral free answer manner with the participants after the experiments. This study revealed the shapes and dimensions regarding easily distinguishable tactile symbols attached to containers and packaging. We expect that this knowledge contributes to improvement of the quality of life of visually impaired persons. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=visual%20impairment" title="visual impairment">visual impairment</a>, <a href="https://publications.waset.org/abstracts/search?q=accessible%20design" title=" accessible design"> accessible design</a>, <a href="https://publications.waset.org/abstracts/search?q=tactile%20symbol" title=" tactile symbol"> tactile symbol</a>, <a href="https://publications.waset.org/abstracts/search?q=containers%20and%20packaging" title=" containers and packaging"> containers and packaging</a> </p> <a href="https://publications.waset.org/abstracts/74619/basic-examination-of-easily-distinguishable-tactile-symbols-attached-to-containers-and-packaging" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/74619.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">219</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">2724</span> Low-Cost Wireless Power Transfer System for Smart Recycling Containers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Juan%20Luis%20Leal">Juan Luis Leal</a>, <a href="https://publications.waset.org/abstracts/search?q=Rafael%20Maestre"> Rafael Maestre</a>, <a href="https://publications.waset.org/abstracts/search?q=Ovidio%20L%C3%B3pez"> Ovidio López</a> </p> <p class="card-text"><strong>Abstract:</strong></p> As innovation progresses, more possibilities are made available to increase the efficiency and reach of solutions for Smart Cities, most of which require the data provided by the Internet of Things (IoT) devices and may even have higher power requirements such as motors or actuators. A reliable power supply with the lowest maintenance is a requirement for the success of these solutions in the long term. Energy harvesting, mainly solar, becomes the solution of choice in most cases, but only if there is enough power to be harvested, which may depend on the device location (e.g., outdoors vs. indoor). This is the case of Smart Waste Containers with compaction systems, which have moderately high-power requirements, and may be installed in places with little sunlight for solar generation. It should be noted that waste is unloaded from the containers with cranes, so sudden and irregular movements may happen, making wired power unviable. In these cases, a wireless power supply may be a great alternative. This paper proposes a cost-effective two coil resonant wireless power transfer (WPT) system and describes its implementation, which has been carried out within an R&D project and validated in real settings with smart containers. Experimental results prove that the developed system achieves wireless power transmission up to 35W in the range of 5 cm to 1 m with a peak efficiency of 78%. The circuit is operated at relatively low resonant frequencies, which combined with enough wire-to-wire separation between the coil windings, reduce the losses caused by the proximity effect and, therefore, allow the use of common stranded wire instead of Litz wire, this without reducing the efficiency significantly. All these design considerations led to a final system that achieves a high efficiency for the desired charging range, simplifying the energy supply for Smart Containers as well as other devices that may benefit from a cost-effective wireless charging system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=electromagnetic%20coupling" title="electromagnetic coupling">electromagnetic coupling</a>, <a href="https://publications.waset.org/abstracts/search?q=resonant%20wireless%20charging" title=" resonant wireless charging"> resonant wireless charging</a>, <a href="https://publications.waset.org/abstracts/search?q=smart%20recycling%20containers" title=" smart recycling containers"> smart recycling containers</a>, <a href="https://publications.waset.org/abstracts/search?q=wireless%20power%20transfer" title=" wireless power transfer"> wireless power transfer</a> </p> <a href="https://publications.waset.org/abstracts/151613/low-cost-wireless-power-transfer-system-for-smart-recycling-containers" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/151613.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">93</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">2723</span> Analysis of Fish Preservation Methods for Traditional Fishermen Boat</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kusno%20Kamil">Kusno Kamil</a>, <a href="https://publications.waset.org/abstracts/search?q=Andi%20Asni"> Andi Asni</a>, <a href="https://publications.waset.org/abstracts/search?q=Sungkono"> Sungkono</a> </p> <p class="card-text"><strong>Abstract:</strong></p> According to a report of the World Food and Agriculture Agency (FAO): the post-harvest fish losses in Indonesia reaches 30 percent from 170 trillion rupiahs of marine fisheries reserves, then the potential loss reaches 51 trillion rupiahs (end of 2016 data). This condition is caused by traditionally vulnerable fish catches damaged due to disruption of the cold chain of preservation. The physical and chemical changes in fish flesh increase rapidly, especially if exposed to the scorching heat in the middle of the sea, exacerbated by the low awareness of catch hygiene; many unclean catches which contain blood are often treated without special attention and mixed with freshly caught fish, thereby increasing the potential for faster fish spoilage. This background encourages research on traditional fisherman catch preservation methods that aim to find the best and most affordable methods and/or combinations of fish preservation methods so that they can help fishermen increase their fishing duration without worrying that their catch will be damaged, thereby reducing their economic value when returning to the beach to sell their catches. This goal is expected to be achieved through experimental methods of treatment of fresh fish catches in containers with the addition of anti-bacterial copper, liquid smoke solution, and the use of vacuum containers. The other three treatments combined the three previous treatment variables with an electrically powered cooler (temperature 0~4 ᵒC). As a control specimen, the untreated fresh fish (placed in the open air and in the refrigerator) were also prepared for comparison for 1, 3, and 6 days. To test the level of freshness of fish for each treatment, physical observations were used, which were complemented by tests for bacterial content in a trusted laboratory. The content of copper (Cu) in fish meat (which is suspected of having a negative impact on consumers) was also part of the examination on the 6th day of experimentation. The results of physical observations on the test specimens (organoleptic method) showed that preservation assisted by the use of coolers was still better for all treatment variables. The specimens, without cooling, sequentially showed that the best preservation effectiveness was the addition of copper plates, the use of vacuum containers, and then liquid smoke immersion. Especially for liquid smoke, soaking for 6 days of preservation makes the fish meat soft and easy to crumble, even though it doesn't have a bad odor. The visual observation was then complemented by the results of testing the amount of growth (or retardation) of putrefactive bacteria in each treatment of test specimens within similar observation periods. Laboratory measurements report that the minimum amount of putrefactive bacteria achieved by preservation treatment combining cooler with liquid smoke (sample A+), then cooler only (D+), copper layer inside cooler (B+), vacuum container inside cooler (C+), respectively. Other treatments in open air produced a hundred times more putrefactive bacteria. In addition, treatment of the copper layer contaminated the preserved fresh fish more than a thousand times bigger compared to the initial amount, from 0.69 to 1241.68 µg/g. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fish" title="fish">fish</a>, <a href="https://publications.waset.org/abstracts/search?q=preservation" title=" preservation"> preservation</a>, <a href="https://publications.waset.org/abstracts/search?q=traditional" title=" traditional"> traditional</a>, <a href="https://publications.waset.org/abstracts/search?q=fishermen" title=" fishermen"> fishermen</a>, <a href="https://publications.waset.org/abstracts/search?q=boat" title=" boat"> boat</a> </p> <a href="https://publications.waset.org/abstracts/160293/analysis-of-fish-preservation-methods-for-traditional-fishermen-boat" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/160293.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">69</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">2722</span> Evaluating of Design Codes for Circular High Strength Concrete-Filled Steel Tube Columns</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Soner%20Guler">Soner Guler</a>, <a href="https://publications.waset.org/abstracts/search?q=Eylem%20Guzel"> Eylem Guzel</a>, <a href="https://publications.waset.org/abstracts/search?q=Mustafa%20G%C3%BClen"> Mustafa Gülen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Recently, concrete-filled steel tube columns are highly popular in high-rise buildings.

The results showed that the EC4 overestimate the axial load capacity for all the specimens. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=concrete-filled%20steel%20tube%20column" title="concrete-filled steel tube column">concrete-filled steel tube column</a>, <a href="https://publications.waset.org/abstracts/search?q=axial%20load%20capacity" title=" axial load capacity"> axial load capacity</a>, <a href="https://publications.waset.org/abstracts/search?q=Eurocode%204" title=" Eurocode 4"> Eurocode 4</a>, <a href="https://publications.waset.org/abstracts/search?q=ACI%20design%20codes" title=" ACI design codes"> ACI design codes</a> </p> <a href="https://publications.waset.org/abstracts/50129/evaluating-of-design-codes-for-circular-high-strength-concrete-filled-steel-tube-columns" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/50129.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">388</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">2721</span> Loop Heat Pipe Two-Phase Heat Transports: Guidelines for Technology Utilization</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Triem%20T.%20Hoang">Triem T. Hoang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Loop heat pipes (LHPs) are two-phase capillary-pumped heat transports. An appropriate working fluid is selected for the intended application temperature range. A closed-loop is evacuated to a high vacuum, back-filled partially with the working fluid, and then hermetically sealed under the fluid own pressure. Heat from a heat source conducts through the evaporator casing to vaporize liquid on the outer surface of the wick structure inside the evaporator. The generated vapor is compelled to vent out of the evaporator and into the vapor line for transport to the condenser assembly. There, heat is removed and rejected to a heat sink to condensed vapor back to liquid. The liquid exits the condenser and travels in the liquid line to return to the evaporator to complete the cycle. The circulation of fluid, and thus the heat transport in the LHP, is accomplished entirely by capillary action. The LHP contains no mechanical moving part to wear out or break down and, therefore possesses, reliability and a long life even without maintenance. In this paper, the author not only attempts to introduce the LHP technology in simplistic terms to those who are not familiar with it but also provides necessary technical information to potential users for the proper design and analysis of the LHP system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=two-phase%20heat%20transfer" title="two-phase heat transfer">two-phase heat transfer</a>, <a href="https://publications.waset.org/abstracts/search?q=loop%20heat%20pipe" title=" loop heat pipe"> loop heat pipe</a>, <a href="https://publications.waset.org/abstracts/search?q=capillary%20pumped%20technology" title=" capillary pumped technology"> capillary pumped technology</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal-fluid%20modeling" title=" thermal-fluid modeling"> thermal-fluid modeling</a> </p> <a href="https://publications.waset.org/abstracts/130646/loop-heat-pipe-two-phase-heat-transports-guidelines-for-technology-utilization" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/130646.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">140</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">2720</span> Experimental Investigation of Folding of Rubber-Filled Circular Tubes on Energy Absorption Capacity</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=MohammadSadegh%20SaeediFakher">MohammadSadegh SaeediFakher</a>, <a href="https://publications.waset.org/abstracts/search?q=Jafar%20Rouzegar"> Jafar Rouzegar</a>, <a href="https://publications.waset.org/abstracts/search?q=Hassan%20Assaee"> Hassan Assaee</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this research, mechanical behavior and energy absorption capacity of empty and rubber-filled brazen circular tubes under quasi-static axial loading are investigated, experimentally. The brazen tubes were cut out of commercially available brazen circular tubes with the same length and diameter. Some of the specimens were filled with rubbers with three different shores and also, an empty tube was prepared. The specimens were axially compressed between two rigid plates in a quasi-static process using a Zwick testing machine. Load-displacement diagrams and energy absorption of the tested tubes were extracted from experimental data. The results show that filling the brazen tubes with rubber causes those to absorb more energy and the energy absorption of specimens are increased by increasing the shore of rubbers. In comparison to the empty tube, the first fold for the rubber-filled tubes occurs at lower load and it can be concluded that the rubber-filled tubes are better energy absorbers than the empty tubes. Also, in contrast with the empty tubes, the tubes that were filled with lower rubber shore deform asymmetrically. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=axial%20compression" title="axial compression">axial compression</a>, <a href="https://publications.waset.org/abstracts/search?q=quasi-static%20loading" title=" quasi-static loading"> quasi-static loading</a>, <a href="https://publications.waset.org/abstracts/search?q=folding" title=" folding"> folding</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20absorbers" title=" energy absorbers"> energy absorbers</a>, <a href="https://publications.waset.org/abstracts/search?q=rubber-filled%20tubes" title=" rubber-filled tubes"> rubber-filled tubes</a> </p> <a href="https://publications.waset.org/abstracts/19152/experimental-investigation-of-folding-of-rubber-filled-circular-tubes-on-energy-absorption-capacity" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19152.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">430</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">2719</span> Poly(S/DVB)HIPE Filled with Cellulose from Water Hyacinth</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Metinee%20Kawsomboon">Metinee Kawsomboon</a>, <a href="https://publications.waset.org/abstracts/search?q=Thanchanok%20Tulaphol"> Thanchanok Tulaphol</a>, <a href="https://publications.waset.org/abstracts/search?q=Manit%20Nithitanakul"> Manit Nithitanakul</a>, <a href="https://publications.waset.org/abstracts/search?q=Jitima%20Preechawong"> Jitima Preechawong</a> </p> <p class="card-text"><strong>Abstract:</strong></p> PolyHIPE is a porous polymeric material from polymerization of high internal phase emulsion (HIPE) which contains 74% of internal phase (disperse phase) and 26 % of external phase (continues phase). Typically, polyHIPE was prepared from styrene (S) and divinylbenzene (DVB) and they were used in various kind of applications such as catalyst support, gas adsorption, separation membranes, and tissue engineering scaffolds due to high specific surface areas, high porousity, ability to adsorb large quantities of liquid. In this research, cellulose from water hyacinth (Eichornia Crassipes), an aquatic plant that grows and spread rapidly in rivers and waterways in Thailand was added into polyHIPE to increase mechanical property of polyHIPE. Addition of unmodified and modified cellulose to poly(S/DVB)HIPE resulting in a decrease in the surface area and thermal stability of the resulting materials. Mechanical properties of the resulting polyHIPEs filled with both unmodified and modified cellulose exhibited higher compressive strength and Young’s modulus by 146.3% and 162.5% respectively, compared to unfilled polyHIPEs. The water adsorption capacity of filled polyHIPE was also improved. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=porous%20polymer"
