This Paper introduces the effectiveness of PC cluster system and PVM technology in solving complicated computational fluid dynamics problems. To emphasize the parallel computation technology of computation fluid dynamics on cluster of computers and the associated problems for load balancing of CFD calculation, The method of the parallel district computation mode is described to simulate a flow field problem and give some conclusions. The results show that the methods, algorithms are correct and can effectively balance the load, and that a quite good parallel efficiency is achieved
