For realizing of PISO program,two typical examples of floating exchanging heat are used to testify the correctness.The convergence and robustness characteristics about PISO,SIMPLE,SIMPLEC,SIMPLER are compared,the results show that the convergence characteristics and the robustness characteristics of the different algorithms are concerned with the given problems.The CPU times of PISO increases because the p″ equations iterating.The convergence characteristics of SIMPLE and SIMPLEC are always inferior to that of PISO and SIMPLER.The robustness characteristics of PISO depend on the given problems.
