摘　　要：降低空气滤清器流动阻力是提高滤清效率、延长滤清器寿命、提高发动机动力性与经济性的主要方法。利用计算流体力学(Computational Fluid Dynamic,CFD)数值仿真分析方法对某型号汽车空气滤清器进行流动阻力仿真分析与研究。通过调整滤清器的进气角度以及圆角设计,提高了滤清器内部气流流动的均匀性,有效降低了滤清器的流动阻力。Reducing the flow resistance of air filter is one of the best way to improve filtration efficiency and longer filter life,to improve engine power and economy.The numerical simulation and structure optimization for the automotive air filter are completed by using computational fluid dynamic（CFD）.We have reduced the flow resistance and improved uniformity of the filter air flow through adjusting the inlet angle of filter and rounded corners.

关 键 词：空气滤清器 计算流体力学 流动阻力
