Abstract

Abstract: A new parallel algorithm of DSMC method with dynamic load balance implementation was introduced using MPI standard library. The parallel efficiency of the two kinds of parallel modes, peer-to-peer mode and master/slave mode, were investigated, respectively. The key points of implementation in unstructured DSMC code using peer-to-peer parallel mode were analyzed. Validity about this method was investigated by analyzing blunt cone flow field. The numerical results confirm the feasibility of method mentioned above.
