The method of streamline curvature is widely used in the analysis of turbomachinery flows.But in the computation of direct problems, we often encounter difficulties. There does notexist a solution when the inlet mass flow is larger than the critical mass one, Which isunknown When the former is close to the latter, we shall meet with computational difficulties,so that considerable effort must be made to obtain the accurate results. In this paper, the exist-ence and uniqueness of the solutions of the direct problems are analyzed and discussed. A newcomputational technique is given, and can be used to compute the critical mass flow. We canthen obtain the solutions of the direct problems under the condition of the critical mass flow.It is proved that the results are of the second order accuracy.
