| 摘 要： | 依据Ｐａｔａｎｋａｒ提出的差分方程稳定性判断的４项基本法则，对可压缩流动的压力修正方程进行了分析，得出压力修正方程系数为正的条件．指出在每一次求解压力修正方程时必须提高解的收敛程度，以保证下一次迭代的差分方程矩阵接近主对角占优．分析了速度离散方程的欠松驰因子对可压缩流压力修正方程的影响．

| Abstract: | The pressure correction equation of compressible flow has been analyzed according to four rules put forward by Patankar. The condition to grantee the coefficients positive of the pressure correction equation has been developed. It has been found that that the solution of the pressure correction equation of each step must be converged to a certain level to keep dia gonal dominance of pressure correction equation of next step. The effects of under relaxa tion factor on pressure correction equation has also been analyzed. |
