Molecular simulation of rarefied supersonic free jets by DSMC method

The direct simulation Monte Carlo method is applied to the study of supersonic jets through a thin orifice. The influence of roughness of the cell network and the number of molecules in a cell on the simulation results is examined. The structure of the jets can be characterized using the rarefaction...

Beschreibung
Zusammenfassung:	The direct simulation Monte Carlo method is applied to the study of supersonic jets through a thin orifice. The influence of roughness of the cell network and the number of molecules in a cell on the simulation results is examined. The structure of the jets can be characterized using the rarefaction parameter introduced by Muntz et al.. The temperature nonequilibrium between the directions parallel and normal to the jet axis is reproduced.
