【 摘 要 】

A collision model for the Direct Simulation Monte Carlo (DSMC) method is presented. The collision model is based on the BGK equation and makes use of the Cercignani2 ellipsoidal distribution to incorporate the effects of heat conductivity. Results obtained by the DSMC method and its BGK and BGKC modifications for a 10deg wedge and a flat plate are presented and discussed.
