摘要：

A treatment of a blade-to-blade flow of nucleating steam in a cascade of supersonic tip section blading by the time-marching method is presented. To reduce the numerical errors associated with the method, an auxiliary mesh is embedded in selected areas of the field thereby increasing the accuracy. The agreement obtained between the solutions and the available experimental results is reasonable.
