Wall Effects in Convective Heat Transfer from a Sphere to Power Law Fluids in Tubes
Heat transfer from a sphere having a uniform temperature and falling axially in a cylindrical tube filled with an incompressible power-law liquid is numerically investigated. The governing equations for simultaneous flow around a confined sphere and heat transfer to power-law fluids were ... 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
COMSOL in a New Tensorial Formulation of Non-Isothermal Poroelasticity
The presence of a moving fluid in a porous rock modifies its mechanical response. Poroelasticity explains how the fluid inside the pores bears a portion of the total load supported by the rock. The remaining part of the load is supported by the elastic skeleton, which contains a laminar ... Read More
Periodic Near-field Enhancement on Metal-Dielectric Interfacial Gratings at Optimized Azimuthal Orientation
The effect of plasmon-wavelength scaled gratings on the surface plasmon resonance is studied experimentally and theoretically. The model samples are multi-layers containing laser fabricated gratings at bimetal-polymer interfaces. Dual-angle dependent surface plasmon resonance ... 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
Using Microwaves for Extracting Water From the Moon
A scientific hypothesis states that cryogenic trapped water is just under the surface of lunar soil at the poles in permanently shadowed craters. Microwave energy can be used to efficiently extract this water from permafrost. COMSOL permits calculation of the heating of simulated lunar ... Read More
The Use of CFD Simulations in Learning Fluid Mechanics at the Undergraduate Level
Simple, accurate CFD simulations using COMSOL Multiphysics are used in a senior-level undergraduate course as a means to explore a number of fluid flows with the intent of developing a deep understanding of the underlying fluid mechanical mechanisms involved in the flows. Students also ... Read More
Rechargeable Battery for Hybrid Diesel-Electric Locomotive
Over time, rechargeable batteries degrade and eventually stop working. You see some combination of declining capacity, rapid self-discharge, and reduced power. Degradation mode depends on battery design, but also on the application. Often, multiple physical processes contribute to ... Read More
2D Extraction of Open-Circuit Impedances of Three-Phase Transformers
This work is concerned with the study of the asymmetrical phenomenon observed in three-phase transformers during the standard short-circuit test. The purpose of our work is to see if the asymmetric measurements can be predicted with the use of 2D finite-element models. To this end, we ... Read More
A Non-isothermal Modeling of a Polymer Electrolyte Membrane Fuel Cell
Polymer electrolyte membrane (PEM) fuel cells have attracted attention as an alternative power source in various applications such as vehicles, portable supplies, and stationary power systems. A non-isothermal PEM fuel model is developed and simulated by using COMSOL Multiphysics. ... Read More
