Abstract
In order to explore whether non-axisymmetric end wall can effectively improve the performance of transonic compressor, a transonic compressor rotor was optimized with the implementation of non-axisymmetric hub endwall contouring by three dimension numerical simulation optimization platform. And this paper described how the compressor flow field was influenced by the non-axisymmetric endwall. The investigation reveals that the non-axisymmetric hub endwall can improve both the efficiency and pressure ratio of the transonic compressor. At the highest efficiency condition, the efficiency increases by 0.31% and the pressure ratio increases by 0.31%. The off-design performance of the compressor is improved.
