In this paper, a fast and accurate multi–grid Euler flow solver was used to simulate flows in an uniform cascade under distorted outlet pressure, flows in nonuniform cascades under uniform boundary conditions, and flows in a nonuniform cascade under nonuniform outlet pressure. Results, including the variation of blade load in the uniform cascade under distorted outlet pressure, the propagation of outlet pressure distortion through the cascade, the flow mechanisms in nonuniform cascades, etc, were obtained. Finally a specific nonuniform cascade was designed, where the inlet pressure nonuniformity induced by outlet pressure distortion was greatly weakened through the cascade, which proves it is possible to reduce the propagation of outlet pressure distortion by a specially designed nonuniform cascade.
