Abstract
The direct simulation Monte Carlo method is applied to the study of superso nic jets through a thin orifice. The influence of roughness of the cell net work and the number of molecules in a cell on the simulation results is exa mined. The structure of the jets can be characterized using the rarefaction parameter introduced by Muntz et al. (AIAA J., 1970). The temperature none quilibrium between the directions parallel and normal to the jet axis is re produced.
