Upgrading the HFIR Thermal-Hydraulic Legacy Code Using COMSOL

I.T. Bodey[1], R.V. Arimilli[1], and J.D. Freels [2]
[1]The University of Tennessee, Knoxville, TN, USA,
[2]Oak Ridge National Laboratory, Oak Ridge, TN, USA

Modernization of the High Flux Isotope Reactor (HFIR) thermal-hydraulic (TH) design and safety analysis capability is an important step in preparation for the conversion of the HFIR core from a high enriched Uranium (HEU) fuel to a low enriched Uranium (LEU) fuel. Currently, an important ... Mehr lesen

Two-dimensional Analysis of Triple Coupled Physics of Structural Mechanics, Diffusion and Heat Transfer in a Gas Pipe

P. Lee-Sullivan[1], and M. Haghighi-Yazdi[1]
[1]Department of Mechanical and Mechatronics Engineering, University of Waterloo, Waterloo, Ontario, Canada

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 ... Mehr lesen

Optimization of Carbon Nanotube Field Emission Arrays

B. L. Crossley[1], M. Kossler[1], P.J. Collins[1], R. A. Coutu Jr.[1], and L. A. Starman[1]

[1]Air Force Institute of Technology, Wright-Patterson AFB, Ohio, USA

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 ... Mehr lesen

Coupled Structural and Magnetic Models: Linear Magnetostriction in COMSOL

J. Slaughter[1]
[1]Etrema Products, Inc., Ames, Iowa, USA

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 ... Mehr lesen

Nanoscale Heat Transfer using Phonon Boltzmann Transport Equation

S. Sihn[1,2], and A.K. Roy[2]

[1]Air Force Research Laboratory, Wright-Patterson Air Force Base, Dayton, Ohio, USA
[2]University of Dayton Research Institute, Dayton, Ohio, USA

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 ... Mehr lesen

COMSOL in a New Tensorial Formulation of Non-Isothermal Poroelasticity

A. Mario-Cesar Suarez[1], and V. Fernando Samaniego[2]

[1]Faculty of Sciences, Michoacan University, Morelia, Mich., Mexico
[2]Faculty of Engineering, National University of Mexico, Mexico City, Mexico

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 ... Mehr lesen

Benchmarking COMSOL - Part 2: CFD Problems

Darrell Pepper
Professor of Mechanical Engineering,
University of Nevada - Las Vegas

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 ... Mehr lesen

Using Microwaves for Extracting Water From the Moon

Edwin Ethridge
Senior Materials Scientist, NASA Marshall Space Flight Center

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 ... Mehr lesen
