Advanced Topics in Acoustics Simulation

M. J. Herring Jensen [1]
[1] COMSOL A/S, Lyngby, Denmark

In this session, we will discuss and showcase a few examples of advanced acoustics applications. In this context, “advanced” means problems that cannot simply be modeled “out-of-the-box,” but require the flexibility and strengths of COMSOL Multiphysics® software. Topics include: • ... Read More

Evaluation of the Shutdown Time of Subsea Pipeline for Oil Transportation new

D. Maciel[1], N. Bouchonneau[1]
[1]Universidade Federal de Pernambuco, Recife, Pernambuco, Brazil

The maintenance plan or rush-to-repair of a subsea pipeline for oil transport may result in the shutdown of the line, in other words, may stop the flow of fluid. During the shutdown, the temperature of the oil tends to decrease continuously, and the heavy molecules tend to crystallize ... Read More

Modeling and Simulation of Hydrogen Generation in Membrane Reactor via Steam Octane Reforming

N. Ghasem [1], A. Y. Alraeesi [1],
[1] UAE Univeristy, Alain, United Arab Emirates

Various hydrocarbon compounds have been converted into pure hydrogen by using a catalyst and a palladium membrane in one reactor (PMR) in a one-step process where the reaction proceeds to almost complete conversion. Octane is converted into pure hydrogen using of a palladium membrane ... Read More

Influence of Electrode Kinetics on Lithium-ion Battery Characteristics

H. Machrafi[1,2], S. Cavadias[2]
[1]University of Liège, Thermodynamics of Irreversible Phenomena, Liège, Belgium
[2]University Pierre et Marie Curie, Laboratoire des Procédés Plasma et Traitement de Surface, Paris, France

The purpose of this work is to show whether an important difference in Lithium solid concentration and electrolyte concentration can be observed in a Lithium-ion battery model, when considering either the Butler-Volmer kinetics or the Tafel kinetics for describing the electrode kinetics ...

Estimation of Hydraulic Conductivity for a Heterogeneous Unsaturated Soil Using Electrical Resistivity and Level-Set Methods new

T. K. Chou[1], M. Chouteau[1], J. S. Dubé[2]
[1]École Polytechnique de Montréal, Montréal, QC, Canada
[2]École de Technologie Supérieure, Montréal, QC, Canada

The estimation of the soil saturated hydraulic conductivity (Ks) is crucial in understanding water flow and transport of contaminants. There are many hydrological techniques available in determining this parameter (constant head method, in-situ soil analysis, etc...). While these ... Read More

Investigating the Performance of Mechanically Ventilated Double-Skin Facades with Solar Control Devices in the Main Cavity new

C. G. Galante[1]
[1]Newtecnic Ltd, London, England, UK

The use of ventilated facades may reduce the cooling and heating energy demands of the building. Double-skin facades (DSFs) belong to the wider group of ventilated facades and currently represent one of the most interesting and studied facade systems. The purpose of this study is to ... Read More

Fluid-Structure Interaction of a Double Curvature Arch Dam Under Seismic Loading by the Application of Added Mass Technique and Acoustic Elements new

R. Manikandan[1], P. Sultana[1]
[1]National Institute of Technology Silchar, Silchar, Assam, India

Fluid Structure Interaction (FSI) plays an important role in the seismic analysis and the design of Hydraulic structures. In this study, the acoustic finite element model is analyzed with impounded water considering appropriate boundary conditions between the water & the upstream face of ... Read More

Voltage and Capacitance analysis of EWOD system using COMSOL

D. Das[1], S. Sohail[1], S. Das[2], and K. Biswas[1]
[1]Electrical Engineering Department, IIT Kharagpur, India
[2]School of Medical Science and Technology, IIT Kharagpur, India

Electrowetting on Dielectrics (EWOD)systems is widely practiced digital microfluidic technique, used in Lab-on-a-Chip (LoC) system for biomedical application. In EWOD, with applied potential, the droplet minimizes its surface energy by transiting towards the actuated electrode. The ... Read More
