Aerodynamic Analysis and Three-Dimensional Redesign of a Multi-Stage Axial Flow Compressor

This paper describes the introduction of three-dimension (3-D) blade designs into a 5-stage axial compressor with multi-stage computational fluid dynamic (CFD) methods. Prior to a redesign, a validation study is conducted for the overall performance and flow details based on full-scale test data, pr...
