摘　　要：运用FLUENT软件对动力外置式对旋风机进行数值模拟,分析其内部流场变化情况,并对该类型对旋风机在不同轮毂比下的流场进行了模拟和分析,通过对比分析得出轮毂比对动力外置式对旋风机的压力、流量、效率等气动性能参数的影响,为对旋风机的优化设计提供相关参考。Numerical simulation of counter- rotating fan with external motor is performed with FLUENT software,the variation conditions of inner flow field are analyzed. Flow field of the counter-rotating fan is simulated and analyzed under different hub- tip ratio,the influence of hub- tip ratio on aerodynamic parameters of counter- rotating fan with external motor are obtained from detail comparisons and analysis,such as total pressure,mass-flow,efficiency.
