Model of a Filament Assisted CVD Reactor

J. Brcka[1]

[1]TEL US Holdings, Inc., Technology Development Center, Albany, New York, USA

In this presentation we are dealing with the computational fluid model of a Filament Assisted Chemical Vapor Deposition (FACVD) reactor. Proposed strategy in this study involved several steps: (a) development a computational model for FACVD process capable to describe and obtain with ... En savoir plus

Linear Convection and Conduction in Cylinders of Water Exposed to Periodic Thermal Stimuli

R.E. Tosh[1], and H.H. Chen-Mayer[1]
[1]National Institute of Standards and Technology, Gaithersburg, Maryland, USA

Primary reference standards for determining absorbed dose to water in radiotherapy beams used at cancer clinics and hospitals ultimately must make reference to the temperature change in water produced by ionizing radiation. The most direct experimental technique for this purpose is water ... En savoir plus

Coupled Heat and Mass Transfer Processes in Enclosed Environments

J.L.Wilson[1], and R. Dwivedi[1]

[1]New Mexico Institute of Mining and Technology, Socorro, New Mexico, USA

Geothermally driven natural convection in enclosures is a ubiquitous process occurring in many physical environments such as caves, mines, etc. We have numerically simulated laminar and turbulent natural convection in isolated air-filled cavities, buried in a more conductive rock mass. ...

Reliability Evaluation for Static Chamber Method at Landfill Sites

H. Ishimori[1], K. Endo[1], and M. Yamada[1]
[1]National Institute for Environmental Studies, Tsukuba, Ibaraki, Japan

In this study, COMSOL Multiphysics was used for the reliability evaluation for static chamber method at landfill sites. Static chamber method, which measures landfill gas emission fluxes, is widely used at landfill sites for the monitoring of greenhouse gas emission such as methane and ... En savoir plus

Reynolds Number Dependent Porous Media Flow Using the Brinkman Equation

R. Rieck[1], A. Bénard[1], and C. Petty[1]
[1]Michigan State University, Michigan, USA

Porous media fluid dynamic modeling has been widely explored and utilized in many academic and industrial applications. Cross flow filtration being one attractive application, whereas the fluid and filtrate flow parallel the porous media, and thereby induce shearing stress along the ... En savoir plus

COMSOL® and MATLAB® Integration to Optimize Heat Exchangers Using Genetic Algorithms Technique

Genetic Algorithms (GA) have proved to be a complete and effective approach for solving optimization problems. This article presents the integration between COMSOL® and a GA optimization tool coded in MATLAB® for the optimization of two thermal systems: a constant area fin in 2D and a ... En savoir plus

Simulation of Manufacturing Process of Ceramic Matrix Composites

S. Yushanov, J. Crompton, and K. Koppenhoefer
ACES of Columbus, LLC, Columbus, OH, USA

Improved performance of aeroengines requires the development of new manufacturing technologies for ceramic matrix composites (CMCs). This has been simulated using COMSOL Multiphysics. Specialized simulation technologies have been developed to describe the infiltration of molten material ... En savoir plus

Non-Isothermal Kinetics of Water Adsorption in Compact Adsorbent Layers on a Metal Support

G. Füldner, and L. Schnabel
Fraunhofer Institute of Solar Energy Systems, Freiburg, Germany

Water adsorption in highly porous materials can be used in heat transformation processes for the efficient use of energy in heat and cold production. One technology for such a thermal heat transformation is the use of water adsorption in highly porous adsorbents like zeolite. To ... En savoir plus
