摘　　要：采用商用计算流体力学(CFD)软件STAR-CDV3.26求解了直径为400mm纸滤芯的空气滤清器三维流速场以及压力场分布,应用高雷诺数k-ε模型封闭雷诺方程,构成二方程模型。计算过程中,采用了压力修正法中的SIMPLE算法。通过分析提出了空气滤清器外部结构的优化方案,对提高通过滤芯的流体流量,降低外壳承受压力有显著效果。In this paper, the velocity and pressure field distribution was predicted using the three-dimensional version of the computational fluid dynamics （ CFD ） code STAR-CDV3.26 on a 400mm diameter paper filter of the air filter. The κ-ε model was adopted to close the Reynolds equation, and construct a turbulent model. In the calculation, the SIMPLE method of pressure speed amending method was adopted. We put forward the optimization project of the air filter outer structure, which had remarkable effect to minish the airflow resistance and reduce the pressure that the crust endure .
