摘　　要：摘要本文推导了气波增压器转子边界条件方程式的求解方法;提出了动边界及其两侧参数的计算途径;编制了NACS程序,利用特征线法对PWS气波增压器转子的流场进行了数值计算.结果表明,本文提出的求解方法是正确可行的,NACS程序是设计计算气波增压器的有力工具.Solutions to the boundary conditional equations of comprex rotator were derived and contact lines and gas parameters on its two sides were calculated. A program NACS was compiled to calculate the flow field in PWS comprex rotator with the method of characteristics and the results showed that the presented methods are correct and effective. Program NACS may be a useful means for design and calculation of comprex supercharger.
