  • The characteristics of flow in wake area and on blade surface had been obtained by experiment and so was the coefficient changing rule in different Reynolds number conditions.The experimental results show that with the Reynolds number decreasing,great changes happen in wake area and to Mach number distribution on blade surface.At the same time,the loss coefficient of cascade increasing rapidly.At low Reynolds number,the turning Reynolds number of this profile is bigger with the inlet Mach number incresaing.The main reason for loss coefficient increasing and great changes in wake area is the flow separation on suction surface in very low Reynolds number condition.
