摘　　要：为提高离心压缩机气动性能,以沈阳某压缩机企业研发的半开式叶轮为原型开展研究,确定子午面型线对叶轮气动性能的影响规律。采用Bézier曲线加载叶片角,实现叶轮几何建模参数化,进而完成对叶轮子午面的气动优化,在原有叶轮基础上进一步提升等熵效率与压缩比,实现叶轮气动性能的提升。研究结果表明,叶片角加载Bézier曲线靠近叶片尾缘的控制点对叶轮气动性能的作用更为显著,优化后叶轮压比、等熵效率同比显著提升,叶轮气动性能得到改善。In order to improve the aerodynamic performance of centrifugal compressors,this paper studies the influence of meridian profile on the aerodynamic performance of the impeller,using a semi open impeller developed by a leading compressor enterprise in Shenyang as the prototype.By using Bézier curves to load blade angles,parameterization of impeller geometric modeling is achieved,and aerodynamic optimization of the meridian surface of the impeller is completed.Based on the original impeller,the isentropic efficiency and compression ratio are further improved,achieving an improvement in the aerodynamic performance of the impeller.The research results indicate that the control point near the trailing edge of the blade with the Bézier curve loading at the blade angle has a more significant effect on the aerodynamic performance of the impeller.After optimization,the pressure ratio and isentropic efficiency of the impeller are significantly improved,and the aerodynamic performance of the impeller is improved.
