摘要
采用C型风管式台架对某发动机冷却风扇气动性能进行试验,得到了该风扇的流量、静压及静压效率的试验数据;利用Fluent软件,对风扇流场进行仿真,得到相应的仿真结果。将仿真结果与测试数据进行对比,结果显示两者差异基本在10%以内,满足工程分析要求。根据风扇内部流场及叶片静压分布的仿真结果,提出了风扇结构优化方案。优化后的风扇静压和静压效率均有明显提升。
The air dynamic performance of mass flow rate,static pressure and static efficiency of an engine fan were obtained by testing with the C-type air duct system and by the simulation of fan flow field with the Fluent software.The difference between the simulation and test results was less than 10%,which meets the engineering accuracy requirements.According to the simulation results of inner flows and pressure distributions on the fan blades,the fan structural optimization was proposed,and the results showed that the optimized fan had higher static pressure and static efficiency.
