With developing of computer and numerical technique,computational fluid dynamics becomes an important branch of the fluid dynamics.The CFD technique spreads quickly with an enhancement of the PC performance and becomes a basic tool for industrial design and analysis.But PC still cannot deal with high performance required field such as research on fluid mechanic details and large-scale industrial design computation.A parallel CFD algorithm based on the PC cluster and Message Passing Interface is presented,which can provide great computational capability.A two-node PC cluster system is constructed,and a data structure system and SPMD parallel code with MPI are developed,including auto domain decomposition,and re-index of element and I-O modules.A classic backing face step case has been done with the program and reasonable results are obtained.The result is also consistent with the serial one of the dominant commercial CFD software Fluent.
