摘要
一、引言 目前常用的求解椭圆型流动问题的方法是S.V.Patankar和D.B.Spalding 1972年提出的SIMPLE算法与后来改进的SIMPLER算法。SIMPLE算法的核心是在交错网格上利用连续方程和动量方程构造了一个近似的压力校正方程来计算压力场并校正速度。由于压力校正方程引入了过多的近似。
A calculation procedure is presented for predicting steady two-dimensional elliptic flows. The method introduces a density-correction concept and a algebraic equation for the velocity correction instead of the trouble-some pressure correction equation in the SIMPLER procedure. Computations show that the method has the same rate of convergence with the SIMPLER while saving about 20% computational effort per iteration. Although the method is described for steady two-dimensional situations, its extension to three-dimensional problems is very straightforward.
