十级高压压气机气动方案设计的优化
Aerodynamic Preliminary Design Optimization of Ten-stage High Pressure Compressor
摘要
Abstract
The efficiency models Firstly,was improved based on the HARIKA program.The stalling pressure rise method pro-posed by C.C.Koch was used to predict stall margin of axial flow compressors.Then,the modified program was applied to cal-culate the characteristic of a ten-stage compressor.The results show that the accuracy of predicting stall margin achieves 99%. Finally,the NSGA-II was used to optimize the overall aerodynamic design.After optimization,the compressor peak efficiency at the design rotational speed increase by 3.4% compared to the initial characters and its surge margin increase from 1 1.6% to 17.6%.The off-design performances also increase by optimizing the angles of both the inlet guide vanes and the former five vanes.The character lines of 90% design rotational speed shows a higher peak efficiency and surge margin after optimization the stator value.关键词
