Use of COMSOL Multiphysics® Software for Physics Laboratory Exercises

H. van Halewijn [1],
[1] Fontys Hogeschool, Applied Physics, Eindhoven, Netherlands

COMSOL Multiphysics® is used to simulate thermal flow experiments at out University for Applied Physics. Students have to measure thermal flow problems and verify the measurements with detailed simulations. The desired accuracy is 5% or less. The presentation will cover 3 laboratory experiments: cooling of an Aluminum rod by natural convection, time dependent heat flow into a container with sand ...

Optimization of a Thermal Actuator for Low Power/Low Cost Applications

R. Zúñiga-Quesada[1], M. Vílchez-Monge[1], P. Vega-Castillo[1]
[1]Instituto Tecnológico de Costa Rica, Cartago, Costa Rica

This work describes the study of a thermal actuator and modifications to the materials employed in order to decrease power consumption and implementation costs. For this study, we worked on improving the thermal actuator described in the work of T. Ebefors. The criteria for choosing the new materials were lower power consumption, commercial availability, and ease processing. The thermal actuator ...

Thermo-mechanical Modeling of Pu-238 Production Target at HFIR

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

The production model in the COMSOL Multiphysics® software makes use of the most up-to-date PIE data, material property inputs, and modeling methodology. The fully coupled thermo-mechanical equations are solved over the entire domain, significantly increasing the degrees of freedom required for a solution, in addition to several other improvements in the computational methodology of the model. ...

Modeling the Behavior of Single Particle during Drying Process

S. Bellur, B. Agasanpura, and C. Coronella
Chemical and Metallurgical Engineering Department, University of Nevada, Reno, Nevada, USA

The aim of the present work is the formulation of a computational model describing transport phenomena in transient biosolids drying. COMSOL Multiphysics was used to perform the simulations, with two spatial dimensions. After a time step of 0.1 s, we found that the solid reached thermal equilibrium with the surrounding gas, which is consistent with empirical correlations.

Thermal Analysis of Electrorefiner for Engineering Scale Pyroprocessing Studies

S. Agarwal, S.P. Ruhela, V. Mente, M.G. Hemanath, B. Murlidhran, V.S. Kumar, C.P. Reddy, G. Ravisankar, B.K. Sharma, K. Nagarajan, C.A. Babu, and P. Kalyanasundaram

Pyrochemical process based on molten salt electrorefining is ideally suited for reprocessing spent metallic fuels from Fast Breeder Reactors. In this work, a heat transfer analysis of the Electrorefiner cell was conducted to develop a basic tool for designing of the engineering–scale Electrorefiner. The focus of this work is to find out steady state temperature profiles of cover gas and molten ...

Investigation of Thermal and Mechanical Factors on Distance Sensors in a Tow Bar

C. Mallwitz [1], L. Fromme [1], B. Sielhorst [2],
[1] University of Applied Sciences Bielefeld, Department of Engineering Sciences and Mathematics, Bielefeld, Germany
[2] Westfalia-Automotive GmbH, Rheda-Wiedenbrück, Germany

Most technical systems become smart over time, therefore those systems will have improved safety and comfort functions. An example is a new development by Westfalia-Automotive. A new generation of smart tow bars, equipped with a sensor system, including distance sensors, is able to inform the driver of a car with a connected trailer about vertical and trailing loads. This helps to ensure a ...

[2]Dipartimento di Ingegneria Aerospaziale e Meccanica, Seconda Università degli Studi di Napoli, Aversa (CE), Italy

A two dimensional instationary analysis of the conjugate optical-thermal fields induced in a multilayer thin film structure on a glass substrate by a moving Gaussian laser source is carried out numerically in order to compare back and front laser treatment processes. COMSOL Multiphysics 3.4 code has been adopted to solve the combined thermal and electromagnetic problem in order to compare the ...

[2]U.S. Army Research Lab, Adelphi, MD, USA

Catalytic micro-combustor represents an exciting area of research for portable power generation. Extensive research is being currently conducted on the design of the reactor and catalyst selection [1]. However another critical element of the design will be a recuperator to minimize losses and provide energy at a more uniform temperature. The mini-recuperator must be both compact and highly ...
