| 摘 要： | 为提高空气滤清器的减阻增效,采用计算流体力学(CFD)模拟技术,结合实验测试的方法,模拟计算颗粒在空气滤清器中的运动轨迹和颗粒在滤清器中沉积的分布率,得出颗粒在滤清器中容易沉积的部位.根据捕集效率实验数据,提出过滤介质捕集效率的多元关联计算式.通过建立二维及三维的CFD模型,模拟计算空气滤清器的流场分布和过滤压力损失,其计算机模拟结果与实验测试结果基本吻合.利用已建立的模拟模型,改变空气滤清器结构参数,替代部分实验模拟研究,得出空气滤清器的过滤压力损失与其各自影响因素的变化规律,以及空气滤清器过滤压力损失与其主要影响因素的单因素关联式.利用大量的模拟数据,回归分析提出空气滤清器过滤压力损失与其结构参数的多元关联计算式.
