Abstract

In order to explore the feasibility of the application of non-axisymmetric static blade in the compressor and the improvement of the distorted flow field, unsteady numerical simulations were used to study the influence of non-axisymmetric stators on compressor performance under uniform and distorted inlet conditions. Results show that non-axisymmetric stators can improve the endwall flow of the stators and reduce the loss. The peak efficiency and pressure ratio of nonaxisymmetric compressor are higher than that of the axisymmetric compressor under the distortion condition. The stability margin of the non-axisymmetric compressor is higher than that of the prototype compressor.

Key words： non-axisymmetric stators; distortion; compressor flow field; numerical investigation
