Gas Flow Simulation at the Molecular Level

	Posted Thu July 19, 2001 @09:42AM
	The Direct Simulation Monte Carlo (DSMC) method is used to simulate rarified gas flows where the continuum Navier-Stokes equations become invalid. The DSMC method works by tracking the interaction of serveral particles, each of which represent a large number of real molecules. GAB Consulting distributes a free Windows PC program for experimenting (in real time) with DSMC.

	The model employs a hard sphere scattering law such that the viscosity is proportional to the square root of the temperature. Furthermore, continuum flow properties can be calculated taking appropriate averages over the velocities and internal energies of the particles. The program allows for a number of shapes (cylinders, flat plates, etc.) to be placed in a number of flow conditions by easily making selections in the user interface.
