For the present CFD, parallel computation is needed because of much calculation work and long time cost in condition of high Reynolds number. Thus a new parallel computing algorithm based on MPI is put forward. According to instances attested,this method is accurate, easy and stable,with higher computing speed and less computing time,which is well adaptable to large-scale scientific computing.%在目前的流体计算中,当雷诺数较高时,计算量非常巨大,存在耗时长的问题,需要采用并行计算,对此提出一种基于MPI(Message Passing Interface)的并行计算方法.通过实例验证,该方法准确、易行、稳健,并且可以大幅提高计算速度,节省计算时间,对于大型科学计算问题具有很好的适用性.
