The Use of CFD Simulations in Learning Fluid Mechanics at the Undergraduate Level

Marc K. Smith
Professor of Mechanical Engineering, Georgia Institute of Technology

Simple, accurate CFD simulations using COMSOL Multiphysics are used in a senior-level undergraduate course as a means to explore a number of fluid flows with the intent of developing a deep understanding of the underlying fluid mechanical mechanisms involved in the flows. Students also ... Mehr lesen

Deep Desulfurization of Diesel Using a Single-Phase Micro-Reactor

G. Jovonavic[1], J. Jones[1], and A. Yokochi[1]
[1]School of Chemical, Biological and Environmental Engineering, Oregon State University, Corvallis, Oregon, USA

This paper describes the benefits of computational fluid dynamics in the development of a microreactor used in the desulfurization of aromatic compounds. It is crucial to verify diffusion and extinction coefficients to ensure accurate simulation results prior to experiments. COMSOL ... Mehr lesen

Error Analysis in Estimating Temperature-Dependent Thermal Diffusivity and Kinetic Parameters using Heat Penetration Data

K.D. Dolan[1,2], A.R. Sommerlot[1], and D.K. Mishra[1]
[1]Department of Biosystems and Agricultural Engineering, Michigan State University, East Lansing, Michigan, USA
[2]Department of Food Science and Human Nutrition, Michigan State University, East Lansing, Michigan, USA

Growing consumer demand for nutraceuticals has stimulated interest by food companies to increase levels of these health-promoting compounds. Thermal processing of canned foods in a retort produces a unique problem: some of the nutraceuticals are highly sensitive to temperature, and ... Mehr lesen

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 ... Mehr lesen

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 ... Mehr lesen

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. ...

Assessment of COMSOL Capabilities to Analyse the Thermo- Hydrodynamic Behaviour of the MSR Core

A. Cammi[1], V. Di Marcello[1], C. Fiorina[1], and L. Luzzi[1]

[1]Nuclear Engineering Division, Department of Energy, Politecnico di Milano, Milano, Italy

The present work is aimed at evaluating the capabilities of COMSOL Multiphysics® to treat heat transfer in Molten Salt Reactors (MSR). The analyzed situation is represented by the molten salt in turbulent regime flowing through a cylindrical channel surrounded by graphite, with both ... Mehr lesen

Modelling Thermal Time-of-Flight Sensor for Flow Velocity Measurement

[1]Institut of Mikroelektronische Systeme, University Duisburg-Essen, Duisburg, Germany
[2]Institut of Elektronische Bauelemente und Schaltungen, University Duisburg-Essen, Duisburg, Germany

This communication reports on a numeric fluid dynamics simulation on a pipe flow model. The basic background is to determine the velocity of a flowing fluid in a pipe by using the Thermal Time-Of-Flight (TTOF) method on water. The visualization of the temperature and velocity ... Mehr lesen

Gravity-Driven Film Flow: Design of Bottom Topography

C. Heining[1] and N. Aksel[1]

[1]Applied Mechanics and Fluid Dynamics, University of Bayreuth, Bayreuth, Germany

We study the gravity-driven film flow of a Newtonian liquid down an inclined plane. Many applications such as heat- and mass exchangers and evaporators or film coaters require undulated or rippled bottom topographies. In these cases, the interplay of gravity, surface tension and inertia ... Mehr lesen

CFD Analysis of Loss Of Vacuum Accident for Safety Application in Experimental Fusion Reactor Facility

C. Bellecci[1], P. Gaudio[1], I. Lupelli[1], A. Malizia[1], M.T. Porfiri[2], R. Quaranta[1], and M. Richetta[1]

[1]EURATOM, Faculty of Engineering, University of Rome “Tor Vergata”, Roma, Italy
