Multiphysics Topology Optimization of Heat Transfer and Fluid Flow Systems
This paper is focused on topology optimization of heat transfer and fluid flow systems for multiphysics objectives. Specifically, COMSOL Multiphysics software is coupled with a method of moving asymptotes optimizer in a custom COMSOL / MATLAB script. Various physical process including ... Read More
Mathematical Modeling of a Lithium Ion Battery
The existing lithium ion battery model in COMSOL’s Multiphysics software is extended to include the thermal effects. The thermal behavior of a lithium ion battery is studied during the galvanostatic discharge process with and without a pulse. The existing lithium ion battery ... Read More
Newtonian and Non-Newtonian Blood Flow over a Backward-Facing Step: Steady-State Simulation
In this work, the fluid flow over a 2D backward-facing step is analyzed in order to provide a case study for the use of different models for the blood dynamic viscosity in COMSOL Multiphysics. Three non-Newtonian models, as well as the Newtonian model are used to study the shear stresses ... Read More
Solid-Liquid Phase Change Simulation Applied to a Cylindrical Latent Heat Energy Storage System
One way of storing thermal energy is through the use of latent heat energy storage systems. One such system, composed of a cylindrical container filled with paraffin wax, through which a copper pipe carrying hot water is inserted, is presented in this paper. It is shown that the physical ... Read More
Two-Dimensional COMSOL Simulation of Heavy-Oil Recovery by Electromagnetic Heating
Introducing heat to the formation has proven to be an effective way of lowering the oil viscosity of heavy oils by raising the temperature in the formation. The application of electrical energy has gained more interest during the last decade because it offers fewer restrictions for its ... Read More
Multiphysics Simulation of a Packed Bed Reactor
Most reactor designs are based on pseudo homogeneous models. This paper studies the COMSOL simulation of a packed bed reactor using a 2-D heterogeneous model. The case considered was a packed reactor with spherical catalyst for oxidation of o-xylene in air to phthalic anhydride. Large ... Read More
Benchmarking COMSOL - Part 2: CFD Problems
Using COMSOL 3.5a, a set of benchmark problems requiring the use of the COMSOL Computational Fluid Dynamics (CFD) module has been simulated. Several of the problems include fluid-heat transfer interactions (Computational Heat Transfer - CHT). The four problems are: flow over a 2-D ... Read More
Nanoscale Heat Transfer using Phonon Boltzmann Transport Equation
COMSOL Multiphysics was used to solve a phonon Boltzmann transport equation (BTE) for nanoscale heat transport problems. One dimensional steady-state and transient BTE problems were successfully solved based on finite element and discrete ordinate methods for spatial and angular ... Read More
Coupled Structural and Magnetic Models: Linear Magnetostriction in COMSOL
Accurate modeling of magnetostrictive materials and devices requires coupling of electrical, magnetic, mechanical, and possibly acoustic domains. There are relatively few finite element software packages that include all these physical models and even fewer that include ... Read More
Reynolds Number Dependent Porous Media Flow Using the Brinkman Equation
Porous media fluid dynamic modeling has been widely explored and utilized in many academic and industrial applications. Cross flow filtration being one attractive application, whereas the fluid and filtrate flow parallel the porous media, and thereby induce shearing stress along the ... Read More
