Investigation of Thermal Contact Gas Gap Conductance Using COMSOL Multiphysics®

J. D. Freels[1], P. K. Jain[1], C. J. Hurt[2]
[1]Oak Ridge National Laboratory, Oak Ridge, TN, USA
[2]The University of Tennessee, Knoxville, TN, USA

Our safety analysis group in the Research Reactors Division of Oak Ridge National Laboratory supports a project to investigate the production of Pu-238 isotope for missions of deep space travel in the High Flux Research Reactor. COMSOL Multiphysics® has been used to support this activity ... Read More

COMSOL Multiphysics® Model of Canine Elbow for Use in Investigating Medial Coronoid Disease

K. A. Bodnyk[1], G. J. Noble[1], N. Fitzpatrick[2], M. J. Allen[3], K. Stephenoff[1], R. T. Hart[1]
[1]Department of Biomedical Engineering, The Ohio State University, Columbus, OH, USA

[3]Department of Veterinary Medicine, The Ohio State University, Columbus, OH, USA

The elbow joint in dogs constitutes a complex interaction of three bones, the humerus, radius and ulna. Medial coronoid disease (MCD) is a common cause of lameness in dogs, i.e. fracturing of the most prominent portion of the ulnar joint surface driven in flexion and in pivot against ... Read More

Electrical Conductivity Modeling and Validation in Unidirectional Carbon Fiber Reinforced Polymer Composites

P. Banerjee[1], J. L. Schmidt[1]
[1]Department of Mechanical Engineering and Materials Science, Washington University in St. Louis, St. Louis, MO, USA

Carbon fiber (CF) reinforced polymer composites (CFRP) have begun to replace Al-Zn-Mg alloys in applications which require high strength-to-weight ratios. The anisotropy of CFRP composites is a result of melt crystallized extrusion techniques that impart an inherent directionality to the ... Read More

Characterization of a 3D Photonic Crystal Structure Using Port and S-Parameter Analysis

M. Dong[1], M. Tomes[1], M. Eichenfield[2], M. Jarrahi[1], T. Carmon[1]
[1]University of Michigan, Ann Arbor, MI, USA
[2]Sandia National Laboratories, Albuquerque, NM, USA

We present a 3D port sweep method in a lossy silicon photonic crystal resonator to demonstrate the capabilities of COMSOL Multiphysics® for frequency domain analysis with input and output ports. This method benefits from the advantages of the S-parameter analysis to characterize the ... Read More

Simulation of Geomechanical Reservoir Behavior during SAGD Process Using COMSOL Multiphysics®

X. Gong[1], R. Wan[1]
[1]University of Calgary, Calgary, AB, Canada

THM (Thermo-Hydro-Mechanical) behavior of the reservoir during SAGD (Steam-Assistant-Gravity-Drainage) was studied through a proper constitutive modeling of the porous media. Specifically, a generalized density-stress-fabric dependent elasto-plastic model with stress-dilatancy and ... Read More

Modeling Scattering from Rough Poroelastic Surfaces Using COMSOL Multiphysics®

A. Bonomo[1], M. Isakson[1]
[1]Applied Research Laboratories, The University of Texas at Austin, Austin, TX, USA

COMSOL Multiphysics® is used to address the problem of acoustic scattering from one-dimensional rough poroelastic surfaces. The poroelastic sediment is modeled following the Biot-Stoll formulation. The rough surfaces are generated using a modified power law spectrum. Both monostatic and ... Read More

Finite Element Modeling of Pulsed Eddy Current Applied to Ferrous and Titanium Fasteners in F/A-18 Airplane Wing Structure

V. K. Babbar[1], P. R. Underhill[1], T. W. Krause[1]
[1]Department of Physics, Royal Military College of Canada, Kingston, ON, Canada

Pulsed eddy current (PEC) is being developed to detect stress corrosion cracks between fasteners on the inner wing spars of the F/A-18 Hornet aircraft. The spars are located below a thick carbon/epoxy wing skin, and so cannot be detected by conventional eddy current techniques without ... Read More

Long-term Effects of Ground Source Heat Pumps on Underground Temperature

X. Zheng[1]
[1]Wayne State University, Detroit, MI, USA

This study set up a numerical model in COMSOL Multiphysics® and simulated the underground temperature over 100 years. The long-term underground temperature around an energy pile was investigated without considering groundwater movement. Parameters and boundary conditions were examined ... Read More

Modeling Revitalization of Atmospheric Water
