    Abstract
  • In order to explore the optimization design method of non-axisymmetric endwall in multistage compressor environment，the non-axisymmetric endwall profiling of the casing endwall and the hub endwall of an embedded stator was studied by numerical simulation optimization and experimental test.The local total pressure loss coefficient of local blade height near the endwall was selected as the objective function.The result proved that compared with the traditional total pressure loss of whole blade height as the objective function，the total pressure loss coefficient of stator can be reduced more in less optimization steps （400 steps），showing that this method can effectively reduce the optimization time and lay a foundation for the engineering application of non-axisymmetric endwall optimization design in multistage compressors.
