针对PISO算法的实现程序,通过2个典型流动换热例子,验证了其正确性,并将PISO与SIMPLE,SIMPLER,SIMPLEC算法的收敛性和健壮性进行了比较.结果表明,不同算法的收敛性和健壮性与具体的问题有关;PISO算法由于在求解过程中增加了p″方程组的求解,使达到收敛耗用的CPU时间增加,SIMPLE,SIMPLEC耗用的CPU时间少;PISO算法的健壮性因不同的问题而异.
Abstract：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.
