This paper studied the endwall profiling in the embedded stator of a multistage compressor, with the method of numerical optimization based on CFD and experimental test under multistage condition. Compared with the whole-blade-height parameter, the partial-blade-height parameter is more suitable as the objective function in improving the endwall flow and reducing the blade loss.
