摘要

摘要: 为探索利用端壁造型提高轴流压气机转子的性能,以亚声速轴流压气机独立转子为对象,将转子等熵效率作为优化目标,对轮毂曲面进行了非轴对称端壁造型优化。对最优结果的流场分析后得出,本文优化后的轮毂壁面在转子吸力面尾缘处低速流区明显缩小,涡流几乎消除,而且降低了局部的逆压差,总体上减弱了尾缘的掺混损失和涡流损失,使得转子等熵效率提高了1.0%。

Abstract: To explore the beneficial usage of profiled endwall in improving the performance of the axial flowcompressor rotor, Using the isentropic efficiency of rotor as the objective, the optimization of non-axisymmetricprofiled endwall was conducted on a subsonic axial flow compressor rotor by CFD simulations.By the flow analysisof the best optimization results, it can be concluded that the low velocity zone was reduced and the radial vortex wasalmost died out closing to suction side of the rotor tail near the hub.The inverse pressure difference was partlyweakened and the mixing flow loss and vortex loss was attenuated on the whole, which increased the isentropicefficiency of the rotor by 1.0%.
