【Abstract】 According to the "General Theory of Three-Dimensional Flow in Turbomachines", the quasi-three dimensional calculation of the transonic flow field has been achieved for a compressor rotor. The calculation is composed of the iteration between the stream function calculations on a mean S2 stream surface and several S1 stream surfaces of revolution in which the artificial compressibility is used for the solution of the transonic flow on S1 and the elliptic equation algorithm is used for the inverse problem of S2. This method appears to be quite efficient. As an example the flow in DFVLR test axial compressor rotor at the design operating condition has been calculated. A properly varying relaxation factor was employed to make the iteration convergent. Through nine cycles of iterations the well convergent result was obtained and was satisfactory in comparison with the measured data.更多还原
