For the development of the research, the local scour that occurs in the pillars of the Continental Bridge (Madre de Dios, Peru) was calculated, analyzed and compared for return periods of 100 and 500 years; The Hec Ras software was used to perform the hydraulic modeling. The development of the article was accomplished by compiling scour calculation methodologies, such as the Colorado State University (CSU) method. Additionally, it was possible to reach the conclusion that, when working with the CSU method, more real values are obtained in terms of local scour. </div> <div> <a data-readmore="{ block: '#abstractTextBlock604068', lines: 2, expandText: '...more', collapseText: '...less' }"></a> </div> <div class="page-number semibold-large-text"> 11 </div> </div> <div class="item-block"> <div class="item-link"> <a href="/AMM.914.29">A Research on the Separation of Sand out of Cassava Slurry by Cyclone</a> </div> <div class="item-link volume-authors"> <div class="semibold-middle-text"> Authors: Khanh Dien Le, Dinh Hai Vu </div> </div> <div id="abstractTextBlock598482" class="volume-info volume-info-text volume-info-description"> Abstract: Monosodium Glutamate (MSG) [1] was invented more than 100 years ago from its first invention in 1908 by Japanese biochemist Kikunae Ikeda, who was trying to isolate and duplicate the savory taste of kombu, an edible seaweed used as a base for many Japanese soups. From 2016, most MSG worldwide is produced by bacterial fermentation in a process similar to making vinegar or yogurt. Sodium is added later, for neutralization. During fermentation, Corynebacterium species, cultured with ammonia and carbohydrates from sugar beets, sugarcane, tapioca (cassava tuber) or molasses, excrete amino acids into a culture broth from which L-glutamate is isolated. In this process, Monosodium Glutamate companies buy cassava [2] pulps from farmers that contain a lot of sand and impurities. In order to increase the productivity with lowest expense, the filtration of sand and solid impurities’ is performed by separation cyclone. In this paper, we study all the measure to design a system of effective pump, cyclone to extract as much as possible all of solid impurities included sand out of cassava slurry before providing to the bacterial fermentation in a process. </div> <div> <a data-readmore="{ block: '#abstractTextBlock598482', lines: 2, expandText: '...more', collapseText: '...less' }"></a> </div> <div class="page-number semibold-large-text"> 29 </div> </div> <div class="item-block"> <div class="item-link"> <a href="/MSF.1047.179">Palm Kernel Shell as Partial Coarse Aggregate Replacement in Asphalt Mixture: Optimum Binder Content and Volumetric Properties Investigation</a> </div> <div class="item-link volume-authors"> <div class="semibold-middle-text"> Authors: Siti Zubaidah Mohd Asri, Faridah Hanim Khairuddin, Choy Peng Ng, Noor Aina Misnon, Nur Izzi Md Yusoff, Ahmad Nazrul Hakimi Ibrahim </div> </div> <div id="abstractTextBlock581301" class="volume-info volume-info-text volume-info-description"> Abstract: Pavement failures such as fatigue, rutting, cracking, bleeding, and stripping are typical pavement deterioration. Researchers have been experimenting with pavement modification to overcome these problems. This study determines the optimum binder content (OBC) for modifying an asphalt mixture with a partial replacement of coarse aggregate (5mm-14mm sieve size) with palm kernel shell (PKS). A 60/70 penetration grade bitumen was mixed with 10, 20 and 30% PKS at selected aggregate gradation following the Public Work Department of Malaysia (JKR/SPJ/2008-S4) specification. The preparation of 60 samples of unmodified and modified asphalt mixture employed the Marshall Method compacted with 75 blows. The OBC was determined based on five volumetric properties of asphalt mixture namely stability, flow, bulk density, void filled with asphalt, and void in total mix. The OBC and volumetric properties of the modified PKS asphalt mixture samples were compared with unmodified asphalt mixture samples in accordance to the specification. Results showed that the OBC sample with 30% aggregate replacement produced the highest OBC value of 5.53% relative to the control sample with 5.40% OBC. The trend for OBC with PKS replacement begins with 10% PKS with 5.30% OBC, 20% PKS with 5.32% OBC and 30% PKS. All volumetric properties of the PKS samples are within the specification limit. Thus, PKS has a promising potential as a coarse aggregate replacement in asphalt mixture. </div> <div> <a data-readmore="{ block: '#abstractTextBlock581301', lines: 2, expandText: '...more', collapseText: '...less' }"></a> </div> <div class="page-number semibold-large-text"> 179 </div> </div> <div class="item-block"> <div class="item-link"> <a href="/KEM.820.159">Mechanical Characterization and Failure Analysis of ABS Material Submitted to Static Tests under the Effect of Temperature</a> </div> <div class="item-link volume-authors"> <div class="semibold-middle-text"> Authors: Abderrazak En-Naji, Nadia Mouhib, Mohamed El Ghorba </div> </div> <div id="abstractTextBlock548483" class="volume-info volume-info-text volume-info-description"> Abstract: In this work, we study the influence of temperature on the mechanical behavior of an amorphous polymer, acrylonitrile butadiene styrene "ABS", based on a series of uniaxial tensile tests on smooth specimens at different temperatures.The results obtained show that the failure of the studied material (ABS) depends strongly on the temperature. Indeed, two zones have been identified: industrial zone T<Tg and thermoforming zone T>Tg (Tg is the glass transition temperature of ABS material).In the industrial zone, we conducted a study of the experimental and theoretical damage via the model of the unified theory. The comparison showed a good agreement concerning the acceleration of the damage process as the temperature increases. In the thermoforming zone, we adopted the same methods to follow the process of flow as a function of the temperature increase. Likewise, we compared theoretical and experimental values which in turn showed a good match. Different stages have been determined in each separate zone, that allows to predict the moment of the critical damage or flow and therefore to intervene in time for a predictive maintenance. </div> <div> <a data-readmore="{ block: '#abstractTextBlock548483', lines: 2, expandText: '...more', collapseText: '...less' }"></a> </div> <div class="page-number semibold-large-text"> 159 </div> </div> <div class="item-block"> <div class="item-link"> <a href="/MSF.957.63">Researches on the Design and Operation of a Magnetic Drive Micropump for the Mixing of Compatible Fluids</a> </div> <div class="item-link volume-authors"> <div class="semibold-middle-text"> Authors: Gabriel Ionuţ Ghionea, Adrian Lucian Ghionea, Constantin Gheorghe Opran </div> </div> <div id="abstractTextBlock545511" class="volume-info volume-info-text volume-info-description"> Abstract: This paper presents the current state of the conception of a magnetic drive micropump, different necessary constructive-technological and functional considerations, 3D modeling using parametric design, main geometric elements of the gears with helical teeth, specific calculations needed to determine the forces loads on the gears and a printed prototype of its model. Researches conducted from an actual micropump version in use led us to the design of an innovative variant, represented by a constructive solution with a driving gear and two driven gears. This ensures the possibility of displacing a fluid mixed of two compatible fluids, but also balancing the loads that appear in the gear mesh during the micropump's operation. This constructive solution is conceived for the size reduction of the pumping installation, for a good homogenization of the two mixed fluids, for an increased reliability of the micropump by reducing wear of moving components in contact, for a reduced noise and vibration. </div> <div> <a data-readmore="{ block: '#abstractTextBlock545511', lines: 2, expandText: '...more', collapseText: '...less' }"></a> </div> <div class="page-number semibold-large-text"> 63 </div> </div> <div class="item-block"> <div class="item-link"> <a href="/MSF.952.250">Computer Modeling Application of Fluid Outflow from Vessels</a> </div> <div class="item-link volume-authors"> <div class="semibold-middle-text"> Authors: Helena Kraváriková </div> </div> <div id="abstractTextBlock542225" class="volume-info volume-info-text volume-info-description"> Abstract: The aim of the paper is to evaluate numerical analysis of the fluid flow during the outflow from vessel orifices at various locations. The problems of the outflow velocities and pressure fields were well-chosen for the given purposes. The selected fluid flow problems were solved by numerical simulation using FEM in ANSYS. For numerical simulation, we used the basic steps to design an abstract model in the ANSYS virtual environment. Numerical simulation requires a geometric model complemented by physical properties of flowing fluids as well as both the initial and boundary conditions. It is then possible to calculate the velocity and pressure fields by numerical simulation for a particular fluid type. The results obtained from the numerical simulation were compared with those of the analytical solution. The results obtained from modeling and numerical simulation correspond to the actual values with minimum deviations. The demonstrated type of the problem solved by numerical simulation and modeling confirmed the advantages and possibilities of flexible solutions for any combination of problems in the field of fluid dynamics. Modeling and numerical simulation of fluid flow can provide results regarding the speed and the pressure fields in vessels and pipelines. </div> <div> <a data-readmore="{ block: '#abstractTextBlock542225', lines: 2, expandText: '...more', collapseText: '...less' }"></a> </div> <div class="page-number semibold-large-text"> 250 </div> </div> <div class="item-block"> <div class="item-link"> <a href="/MSF.941.1546">Traveling Waves Induced by Sweeping Flows on Solidification Interfaces</a> </div> <div class="item-link volume-authors"> <div class="semibold-middle-text"> Authors: Alain Pocheau, Tania Jiang, Marc Georgelin </div> </div> <div id="abstractTextBlock533663" class="volume-info volume-info-text volume-info-description"> Abstract: Solidification of alloys in a thermal gradient usually involves the generation of flows by thermal or thermosolutal convection. We experimentally study their effects on the dynamics of a solidification interface by inducing a controlled sweeping flow in a directional solidification device. Flow is induced in the sample from an external thermosiphon. Downstream inclination of microstructures and downstream sidebranch development are observed. However, the major outcome is the evidence of large scale travelling waves on the solidification interface. They are induced by the coupling between solidification and flow and yield repetitive striations of the solid phase. Two waves are observed and characterized. </div> <div> <a data-readmore="{ block: '#abstractTextBlock533663', lines: 2, expandText: '...more', collapseText: '...less' }"></a> </div> <div class="page-number semibold-large-text"> 1546 </div> </div> <div class="item-block"> <div class="item-link"> <a href="/KEM.789.176">A Study on the Flow Characteristics and Quality Control of Lightweight Foamed Magnesia Composite Using Super Absorbent Polymers as Base Material for Biological Panels</a> </div> <div class="item-link volume-authors"> <div class="semibold-middle-text"> Authors: Sung Rok Oh, Chulgoo Lee, Yung Wang Choi </div> </div> <div id="abstractTextBlock539783" class="volume-info volume-info-text volume-info-description"> Abstract: In this paper, the flow characteristics of a lightweight formed magnesia composite usingsuper absorbent polymer as base material for biological panels were evaluated.
