摘要
针对复杂区域中流动计算的SIMPLE算法,在选用不同的速度分量作为求解变量和离散体元的界面速度时,进行了算法收敛速度及收敛准确性的对比分析。通过研究,澄清了现有算法中存在的概念失误,提出改进算法的措施,并给出算例。
With the choices of dependant variables and cell face velocity, the convergency speed and computational accuracy of SIMPLE algorithm employed in the computation of complex flows are analyzed. The mistakes of basic concepts found in literature are corrected, and a method whose good effects in improving the algorithm showed by numerical tests, is put forward.
