摘　　要：为了研究双级旋流管空气滤的适宜滤清效率,对双级旋流管空气滤进行了仿真分析和试验研究,试验结果表明:双级旋流管空气滤的重量效率达到98%以上,对10μm以上粒子的分离效率达到90%以上,与仿真结果相差13%.仿真和试验结果证明新型双级旋流管空气滤能够满足压气机前端对进气过滤重量效率要求,可在此基础上进一步研究旋流管空气滤适宜滤清效率.In order to study the appropriate efficiency of the two-stage cyclone air cleaner, CFD simulation and experimentation were carried out on the two-stage cyclone air cleaner. The results showed the weight efficiency was about 98%,and the separation efficiency for particles larger than 10μm was90%,which met the requirements of the Turbo Charge. The discrepancy between CFD simulation and experimentation results was about 13%. Finally,study on the appropriate efficiency of the cyclone air cleaner was pointed out.
