摘要： 建立了重型卡车空气滤清器前进气系统内部三维流域模型。采用计算流体动力学两相耦合的方法，研究了不同结构、单叶片流道、叶片轮轴对前进气系统流场特性和过滤效率的影响，优化了前进气系统的参数。研究表明：随着叶片轮轴几何直径参数的增加，整体平均压力降呈现先缓慢上升后突然升高的趋势；滤清效率呈现一高一低双峰变化的趋势。最终确定最优结构为叶片轮轴几何直径参数为57.78 mm时，粒级效率较原结构明显提高，滤清效率较原结构提高10.07%。

Abstract: The internal 3D fluid model of the forward intake system of the heavy truck air filter was built. By using the two-phase coupling method of computational fluid dynamics, the effects of different structures, single blade channel and blade axle on the flow field characteristics and filtration efficiency of the forward intake system were studied, and the parameters of the forward intake system were optimized. The research shows that: with the increase of the geometric diameter parameters of the blade axle, the overall average pressure drop trends to increase slowly first and then rise suddenly; the filtration efficiency shows a trend of high and low bimodal changes. Finally, when the geometric diameter parameter of the blade axle is 57.78mm, the particle efficiency is significantly improved and the filtration efficiency is increased by 10.07%, compared with the original structure.
