摘要
基于数值分析方法对跨音速高负荷轴流风扇的前缘及翼型中线进行了优化及结果分析,结果显示:激波为跨音转子做功的直接动力.其直接影响到风扇转子的性能。风扇翼型前缘形状及翼型中线形状显著影响激波强度、影响范围、激波附面层分离现象。经优化后风扇等熵效率显著增加,由46.43%〜81.03%提升至56.27%〜84.6%。
Based on the numerical analysis method,the leading edge and airfoil center line of the transonic high load axial fan are optimized and the results are analyzed.The results show that the shock wave is the direct power of the transonic rotor,which directly affects the performance of the fan rotor.The shape of the leading edge and the center line of the fan airfoil significantly affect the shock waves intensity,influence range and shock wave boundary layer separation.After optimization,the isentropic efficiency of the fan is increased significantly from 46.43%〜81.03%to 56.27%〜84.6%.
