Numerical study of improving capability of compressor with inlet-distortion

Based on the theory of 'two generation of unsteady flow type', the function of improving 2D cascade's capability by bringing in prompting with a uniform inlet flow has be validated. With the same procedure, study of the effects on capability with a distorted inlet flow is the emphases of this dissertation. With either uniform inlet flow or distortion inlet flow, the results show that the flow field would be ameliorated by bring in prompting, therefore the aerodynamic parameter would vary to a better quantity, such as the total pressure improve and efficiency being increased even when there is a small flux.
