【Abstract】 By comparing the pseudostream functions with the stream functions, and stream like functions on theory, it is indicated that the pseudostream function method has some advantage in solving a three-dimensional flow field. In the transonic case, the momentum equation which has not been used as the principal equations of pseudostream functions is employed to calculate the density to make the density determined uniquely. The numerical example show that the method is simple and effective to solve subsonic and transonic flow.更多还原
