Streamer Propagation in a Point-to-Plane Geometry

M. Quast[1] and N.R. Lalic[1]
[1]Gunytronic GmbH, St Valentin, Germany

Corona discharge is used in several applications such as surface treatment of polymers, photocopying or dust removal in air conditioning. Streamer formation is undesirable for most of these applications. Therefore, several studies have been dedicated to investigate the formation and ... Read More

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 ... Read More

Magneto-hydrodynamic Flow in Electrolyte Solutions

M. Qin[1], and H. Bau[1]
[1]Department of Mechanical Engineering and Applied Mechanics, University of Pennsylvania, Pennsylvania, USA

The paper presents and compares two models for simulating magneto-hydrodynamic flow of RedOx electrolyte in a conduit patterned with circular pillars. The first model solves the coupled Nernst-Planck and Navier-Stokes equations subjected to Butler-Volmer electrode kinetics and provides ... Read More

The Role of COMSOL Toward a Low-Enriched Uranium Fuel Design for the High Flux Isotope Reactor

J.D. Freels[1]
[1]Oak Ridge National Laboratory, Oak Ridge, Tennessee, USA

Design and safety analyses are underway to convert the High Flux Isotope Reactor (HFIR) at the Oak Ridge National Laboratory (ORNL) from a high-enriched uranium (HEU) fuel to a low-enriched uranium (LEU) fuel. The primary constraint for the project is that the overall fuel plate ... Read More

Multiphysics Topology Optimization of Heat Transfer and Fluid Flow Systems

E. Dede[1]
[1]Toyota Research Institute of North America, Ann Arbor, Michigan, USA

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

Design and Optimization of an All Optically Driven Phase Correction MEMS Deformable Mirror Device using Finite Element Analysis

V. Mathur[1], K. Anglin[1], V.S. Prasher[1], K. Termkoa[1], S.R. Vangala[1], X. Qian[1], J. Sherwood[1], W.D. Goodhue[1], B. Haji-Saeed[2], and J. Khoury[2]

[1]Photonics Center, University of Massachusetts-Lowell, Lowell, Massachusetts, USA
[2]Air Force Research Laboratory/Sensors Directorate, Hanscom Air Force Base, Massachusetts, USA

Optically addressable MEMS mirrors are required for future high density adaptive optics array systems. We have demonstrated a novel technique of achieving this by actuating low stress Silicon Nitride micro mirrors via cascaded wafer bonded Gallium Arsenide photo detectors on Gallium ... Read More

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 ... Read More

Modeling of Shrinkage Behavior in Cement Paste Using Thermal-structural Interaction

T. Chen[1], and P.G. Ifju[1]

[1]University of Florida, Gainesville, Florida, USA

This paper describes using thermal-structural interaction to model the shrinkage behavior in cement paste under drying. An inverse method of combining the finite element analysis and the least-squares method is implemented to fit experimentally determined shrinkage in order to obtain ... Read More

Three-Dimensional Simulation of Signal Generation in Wide-Bandgap Semiconductor Radiation Detectors

J. E. Toney[1]
[1]Pennsylvania State University Electro-Optics Center, Freeport, Pennsylvania, USA

We demonstrate the use of Comsol Multiphysics with Matlab to model signal generation in wide-bandgap semiconductor radiation detectors. A quasi-hemispherical detector design is compared with a simple, planar detector. Results show that the quasi-hemispherical design can simply and ... Read More
