The understanding of quench, or the sudden transition to the normal state of a high-current Superconductor (SC), is fundamental for the design of a SC magnet, and it is widely discussed in the literature. This paper presents some simple COMSOL models, which are compared with well-known ... Read More
Two-dimensional Analysis of Triple Coupled Physics of Structural Mechanics, Diffusion and Heat Transfer in a Gas Pipe
In this study, a 2-D model has been built using COMSOL Multiphysics® to analyze a triple coupled physics problem involving simultaneous gas diffusion, heat transfer, and structural mechanics in a pipe due to the flow of high-pressure carbon dioxide. The problem geometry and boundary ... Read More
Optimization of Carbon Nanotube Field Emission Arrays
Carbon nanotubes (CNTs) have been proven experimentally to be well suited for field emission applications. An optimized triode configured CNT field emission array is developed using the COMSOL Multiphysics Electrostatics Application to adjust five key physical dimensions to investigate ... 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 magnetostrictive ... 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
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
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: 1. 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
Electro Magnetic Wave Simulation in Fusion Plasmas
Fusion is a form of nuclear energy which has impressive advantages from the point of view of fuel reserves, environmental impact and safety. If successful, fusion energy would ensure a safe, resource conserving, environmentally friendly power supply for future generations. In a world ... 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
