Multiphysics Modeling Solutions for Advanced Vehicle Research & Development

Ercan Dede currently works as a Principal Scientist for the Toyota Research Institute of North America, where his research involves the multiphysics simulation and optimization of electromechanical systems for advanced vehicle applications. Dr. Dede received his Ph.D. and B.S., respectively, in 2007 and 1998 in Mechanical Engineering from the University of Michigan. From 1998 to 2003 he ...

Parametric Study of Electrolyte-Supported Planar Button Solid Oxide Fuel Cell

Fuel cells are devices that convert chemical energy of a fuel into electrical energy through electrochemical processes. One of the types of fuel cell is the Solid Oxide Fuel Cell (SOFC) that uses solid ceramics for electrolytes. Numerical simulation involves constructing a mathematical model of the SOFC and use of specifically designed software programs that allows the user to manipulate the ...

Modeling Pit Lake Flooding After Mine Closure

[1]Amphos 21, Barcelona, Spain

Most of mining works, either on the surface or in the underground, demand continuous groundwater pumping in order to operate under dry conditions. When the mining activity stops, dewatering also stops and mining facilities begin to flood, quite quickly at the beginning but becoming slower as the water level in the pit lake rises. The rise of the surface of the lake decelerates due to the bigger ...

FSWR Microlith Performance Metrics Assessment

[1]NASA, Marshall Space Flight Center, Huntsville, AL, USA

COMSOL Multiphysics® has been used to develop assessment tools for the NASA-sponsored Precision Combustion, Inc. (PCI) regenerable Microlith®- based adsorber modules. The Full Scale Water Removal (FSWR) PCI Microlith® was initially modeled for comparison with exit velocity data, measured while exterior canister was removed. Measurement data as well as flow analysis showed that the velocity ...

Evaluation of Performance of Enzymatic Biofuel Cells with Microelectrode Arrays Inside a Blood Artery via Finite Element Approach

C. Wang[1], Y. Song[1]
[1]Florida International University, Miami, FL, USA

Enzymatic biofuel cells (EBFCs) are considered as a promising candidate for powering miniature implantable devices. In order to predict the performance in the human blood artery, we simulated a 3D EBFC chip with highly dense micro-electrode arrays. In this simulation using COMSOL Multiphysics®, we applied the 1) Michaelis Menten equation; 2) Nernst potential equation; 3) Navier Strokes velocity, ...

3D Multiphysics Analyses to Support Low Enriched Uranium (LEU) Conversion of HFIR - new

[1]Oak Ridge National Laboratory, Oak Ridge, TN, USA

Engineering design studies of the feasibility of conversion of the High Flux Isotope Reactor (HFIR) from high-enriched uranium to low-enriched uranium (LEU) fuel are ongoing at Oak Ridge National Laboratory as part of an effort sponsored by the U.S. Department of Energy’s Global Threat Reduction Initiative Reduced Enrichment for Research and Test Reactors program. COMSOL Multiphysics® models are ...

Modeling of Noise Produced by Offshore Wind Turbines with Different Foundations and Effects on the Marine Environment - new

B. Marmo [1], I. Roberts [1]
[1]Xi Engineering Consultants, Edinburgh, Scotland, UK

Vibration produced by offshore wind turbines during their normal operation transmits through the tower into the foundation where it interacts with the surrounding water and is released as noise. The noise produced by offshore wind turbines can be detected by fish and marine mammals and may lead to alteration of their behavior. Given that noise is emitted at the interface between the foundation ...

Parameter Estimation of Anisotropic Diffusion in Clay with COMSOL Multiphysics® - new

R. Gerasch[1], J. Kulenkampff[1], J. Lippmann-Pipke[1]
[1]Helmholtz-Zentrum Dresden-Rossendorf, Institute of Resource Ecology, Research Site Leipzig, Leipzig, Germany

Our GeoPET camera is explicitly dedicated for and well capable of 4D monitoring of solute transport in dense geological material, c = c(x,y,z,t) [1-4]. We apply COMSOL Multiphysics® for reproducing our experiments and extracting parameter sets for our 4D problems [5-6]. By aligning simulated results of anisotropic diffusion in clay to our observations we are able to clearly differentiate and ...

Paleohydrogeological Reactive Transport Model of the Olkiluoto Site (Finland) - new

[3]Posiva, Eurajoki, Finland

The safety assessment of the deep geological repository for nuclear waste of Olkiluoto (Finland) requires the evaluation of the influence of the land uplift (ice withdrawal) in groundwater. With this objective in mind, we have developed a three dimensional reactive transport model of the Olkiluoto, simulating the most relevant deformation zones in a three-dimensional domain. The evolution in ...
