| 摘 要： | １．引 言 多年计算实践表明，对于叶轮机械跨音流场的数值模拟，有限体积Ｄｅｎｔｏｎ格式是最有效的计算方法之一．以文［２］为基础，本文在算法上对Ｄｅｎｔｏｎ格式作出改进，这包括修正格式中的松弛因子、拟流线方向的平滑以及出口区网格调整三个问题．其次我们选定了三个典型平面叶栅算例，校对审定叶型数据及实验数据，并确定精度考核标准，试图对计算精度有一个定量估计．再以变动出口压力的数值试验方法，确定了通过平面叶栅之最大流量．数值试验表明，算法改进使程序的求解能力有相当大的提高，对多个算例、不同粗细网格及工况变…

| Abstract: | Some numerical tests are finished in this paper for raising the ability to find solutions of Denton-scheme. First, three improvement opinions of concrete algorithm for Denton-Scheme are presented. Then, the computational accuracy of numerical solutions is checked with three typical examples, also a quantitative estimation for computational accuracy is described. Finally, the maximum flux of mass through plane cascades is determined by numerical tests. A lot of tests shows that the ability to find solutions of this program is fairly raised with algorithm improvements of this paper. |
