摘　　要：随着叶轮机械向高膨胀比、高效率的方向发展,叶轮机械级内部越来越多地出现跨音速流动现象。利用数值计算模拟叶轮机械内部的超、跨音速流动,降低激波损失和强度,对提高超、跨音速叶轮机械的性能具有重要意义。With the high expansion ratio and high efficiency development of turbomachine, the transonic flow phenomenon appears in turbomachine more and more. It has important significance to enhance the super and transonic turbomachine performance that using the numerical computation technique simulates the flow in super and transonic turbomachine for decreasing the loss and strength of shocks.
