摘　　要：采用CFD数值模拟方法研究了不同结构形式集流器对大型轴流式风机性能的影响。计算得到了风机压升和效率随流量变化的性能曲线,对比分析了不同结构形式集流器对风机性能影响的原因,为合理设计与选择集流器形式改善风机性能提供了依据。The influence of couectors with different structure forms on large type axial flow fan performance was studied by using CFD numerical simulation method. The performance curve of fan pressure rise and efficiency changeable with flow was calculated and obtained. The effects of different collector forms on fan performance were compared and analyzed, it provided the gist for well design and reasonable choose for improving the performance of axial flow fan.
