1results about How to "Improve performance parameters" patented technology

The application provides a compressor non-axisymmetric end wall shaping method based on an adjoint shape optimization, and belongs to the technical field of aero-engine compressor design, in particular to: taking an axisymmetric end wall compressor as an optimization object, sequentially completing a cascade single-channel original geometric model establishment, structured grid division, obtaining the isentropic efficiency of the compressor designed by using the axisymmetric end wall through flow field simulation, establishing an optimization target and a constraint condition, solving the sensitivity of a design variable based on an adjoint shape optimization method, arranging control points on the outer surface of the end wall, combining the total displacement amount of the control points with the sensitivity calculation, realizing the end wall grid deformation through a radial basis function, iteratively optimizing the performance of the current end wall geometric configuration through simulation verification, and until the end wall meets the optimization target and the constraint condition. The application improves the optimization efficiency and shaping precision of the compressor end wall, improves the isentropic efficiency of the compressor, and guarantees the stability of the performance parameters of the optimized compressor.
