MONTE-CARLO SIMULATION IN AN ENGINEERING CONTEXT

Abstract

The computational and physical requirements for the successful application of the direct simulation Monte-Carlo method to typical engineering flows, as opposed to earlier applications to artificial test cases, are discussed. An outline is given of the changes that have occurred in the program structure as a result of both altered requirements and advances in computer technology. The accumulated experience from applications of the classical molecular models is reviewed. It is shown that requirements for the accurate modeling of engineering flows are best met by a new molecular model called the variable hard sphere, or VHS, model, The necessary kinetic theory for the application of this model is presented.
