FEM Convergence for PDEs with Point Sources in 2-D and 3-D

M. Gobbert [1], K. M. Kalayeh [2], J. S. Graf [1],
[1] Department of Mathematics and Statistics, University of Maryland - Baltimore County, Baltimore, MD, USA
[2] Department of Mechanical Engineering, University of Maryland - Baltimore County, Baltimore, MD, USA

Numerical theory provides the basis for quantification of the accuracy and reliability of a FEM solution by error estimates on the FEM error vs. the mesh spacing of the FEM mesh. This paper presents techniques needed in COMSOL Multiphysics® software to perform computational studies for ... En savoir plus

Finite Element Modeling of Eddy Current Probes for CANDU® Fuel Channel Inspection

M. S. Luloff [1], T. W. Krause [2], J. Morelli [1],
[1] Queen's University, Kingston, ON, Canada
[2] Royal Military College of Canada, Kingston, ON, Canada

CANDU® reactor pressure tubes (PT) contain D2O, which is used as a moderator. Surrounding the PTs are gas-filled Calandria Tubes (CT), which thermally isolate the PTs from the moderator surrounding the fuel channels. If the garter springs move apart, the PT will sag into the CT. Under ... En savoir plus

A Systematic Method for Producing Simulated Scattered Field Data from Known Structures

R. S. Ritter [1], M. A. Fiddy [2],
[1] Olivet Nazarene University, Bourbonnais, IL, USA
[2] University of North Carolina - Charlotte, Charlotte, NC, USA

One of the greatest challenges in developing algorithms for imaging from scattered fields is the lack of suitable scattered field data from known targets. It has proved quite difficult to acquire this data from measurements in the laboratory due the fact it can be costly, time ... En savoir plus

PA Loudspeaker System Design Using Multiphysics Simulation

R. Balistreri [1],
[1] QSC Audio Products, LLC., Costa Mesa, CA, USA

This paper utilizes lumped circuits equivalent and pressure acoustics to simulate the behavior of a PA loudspeaker in order to improve its design. En savoir plus

Single-Phase Modeling in Microchannel with Piranha Pin Fin

X. Yu [1], C. Woodcock [1], Y. Peles [2], J. Plawsky [1],
[1] Rensselaer Polytechnic Institute, Troy, NY, USA
[2] University of Central Florida, Orlando, FL, USA

Microchannel has shown potential to dissipate high heat flux in past years [1][2]. At the same time, liquid cooling attracts more and more attention from researchers for its favorable thermal properties and ability to cool down hot and keep acceptable system temperature [3][4][5]. This ... En savoir plus

Simulation of the Cooling and Phase Change of a Melt-Cast Explosive

W. Sanhye [1], C. Dubois [1], P. Pelletier [2], I. Laroche [2],
[1] Department of Chemical Engineering, École Polytechnique de Montréal, Montréal, QC, Canada
[2] General Dynamics Ordnance and Tactical Systems-Canada Inc., Repentigny, QC, Canada

Introduction Numerical modeling of melt-casting is becoming a popular tool for the energetic materials and explosives industry. Compared to traditional metal casting, the cooling cycle for explosive melts is significantly longer because of their high Prandtl numbers [1]. Improving the ... En savoir plus

Numerical Investigation of Heat Transfer in an Attic Duct Model

H. Liu [1], A. Fallahi [1], J. Kosny [1]
[1] Fraunhofer Center for Sustainable Energy Systems, Boston, MA, USA

Air ducts play an important role in the energy efficiency of residential homes across the country. While transporting the conditioned air from the HVAC system to the conditioned space, 30-40% of the thermal energy can be lost due to conduction [1]. The loss of thermal energy can reduce ...

Microscale Simulations of Catalyst Deactivation During Gas-Phase Upgrading of Biomass Pyrolysis Vapors

P. N. Ciesielski [1], D. Robichaud [2], B. Donohoe [1], M. Nimlos [2],
[1] Biosciences Center, National Renewable Energy Laboratory, Golden, CO, USA
[2] National Bioenergy Center, National Renewable Energy Laboratory, Golden, CO, USA

Catalytic fast pyrolysis is a process by which biomass may be converted into liquid hydrocarbon transportation fuels and chemical co-products that are alternative to their petroleum-derived counterparts. Chemical compounds in raw pyrolysis vapor have high oxygen content and therefore ... En savoir plus

PVDF Piezoelectric Nanofibers as Hair Cell Substitutes: A Feasibility Study

C. R. Pérez [1], J. J. Santiago-Avilés [2],
[1] Department of Materials Science and Engineering, University of Pennsylvania, Philadelphia, PA, USA
[2] Department of Electrical and Systems Engineering, University of Pennsylvania, Philadelphia, PA, USA

Sensorineural hearing loss is the most common sensory deficit in the world, and within this category damage or loss of the primary sensory cells of the inner ear, known as hair cells is the most common cause [1]. Partial hearing loss is addressed by the use of hearing aids, electronic ... En savoir plus

Simulation of a Dual Axis MEMS Seismometer For Building Monitoring System

M. A. Shah [1], F. Iqbal [1], B. L. Lee [1],
[1] Korea University of Technology and Education, Cheonan, Chungcheong, South Korea

A dual axis MEMS seismometer targeted for building monitoring system has been simulated for a full scale of ±5g acceleration. The design uses the capacitive effect for vibration sensing. This comb drive capacitive MEMS seismometer consists of 8 springs with two proof masses. The device ... En savoir plus
