[0258] Example description:
[0259] Using the developed end wall optimization platform, combined with the end wall parametric modeling method, the end wall of the compressor cascade is optimized non-axisymmetrically, and the effect of non-axisymmetric end wall technology on the internal flow of the cascade is initially explored. Finally, the feasibility of the present invention is verified by a comparative analysis with the reference end wall (flat end wall).
[0260] In view of the three-dimensional aerodynamic numerical optimization process in impeller machinery, the key technologies and difficulties in the optimization design of the end wall shape of the high-load fan / compressor can be summarized as follows:
[0261] 1) CFD numerical simulation in the optimization iteration process is very time-consuming
[0262] Aiming at the three-dimensional aerodynamic numerical optimization problem in impeller machinery, by establishing an approximate model for optimizing independent variable...
