摘　　要：为获得流动性能和噪声性能的优化,对多翼离心风机叶片、进口集流器和蜗舌进行了改进,并采用CFD数值模拟软件FLUENT对这些机型进行了模拟计算,通过对其流场进行对比分析得到了两台流动和噪声性能均比原风机显著提高的机型。For the optimization purpose of obtaining of flow and noise performances, the structure of blade, inlet bell mouth and volute tongue of multi-blade centrifugal fan are improved. And the CFD simulation software FLUENT to simulate and calculate numerical is adopted these fans. After comparing and analyzing the flow field, it is obtained two fans whose flow and noise optimized significantly original fans. performances are compared to the
