A Summary of Developments of the Mean-Streamline Method in China

The mean-streamline method (MSLM) proposed by Wu more than 30 years ago has been further developed in many ways in China since the fifties. Major progress in this method is summarized here. This progress includes: a completely analytical solution of the inverse problem which is extremely quick and more accurate than the original solution, the extension of MSLM to the axisymmetrical flow channels, the extension of the calculation range to transonic flow and nonisentropic flow, the estimation of applicable limits of MSLM, the improvement of MSLM with higher order derivatives, and the development of practical computer programs. The comparison of the calculation results with the experimental data is good, and the method has been widely applied in China with good success.
