中文摘要：
通过六个典型流动换热问题对CLEAR、SIMPLE、SIMPLEC和SIMPLER四种算法进行收敛性和健壮性比较。在相同的数值处理方法下，收敛所用CPU时间多少用来判断算法的收敛特性；能得到收敛解的时步倍率范围大小用来比较算法的健壮性。比较结果表明，对于开口系统SIMPLEC算法综合效果较好，而闭口系统CLEAR算法综合占优。
英文摘要：
Comparisons of the convergence and robustness characteristics between CLEAR algorithm and SIMPLE, SIMPLEC, SIMPLER algorithms through six typical flow and heat transfer problems are conducted. At the conditions of the same numerical treatments of all other aspects, the CPU time and the region of the time step multiple for obtaining a converged solution are compared. The results of the comparison show that SIMPLEC is the better algorithm in opened system while CLEAR is better for closed system.
