摘要
依靠经验和半经验设计燃料电池汽车空气过滤器需要耗费大量的精力和财力,且设计周期长.本文利用计算流体动力学(CFD)软件STAR—CCM+,建立了空气过滤器的三维数值计算模型.运用多孔介质模型模拟活性炭区域的内部流动,对空气过滤器的稳态流动进行了数值模拟,对不同结构的空气过滤器的气体流动分布、流动均匀性进行数值计算.并提出有利于活性炭利用率的优化方案,为燃料电池汽车空气过滤器结构设计和性能改进提供理论依据.
The air filter designing of fuel cell vehicle with experiment and principle needs a lot of energy and finance,and the design cycle is long.This paper established the mathematical 3D model of air filter based on the CFD software of STAR-CCM＋.By using porous media approach to simulate the internal flow of active carbon zone and conducting mathematical simulation of steady flow of the air filter,this paper conducted mathematic simulation of flow distribution and flow uniformity index inside the filter with different structure.What＇s more,this paper proposed an optimized filter structure to increase the utilization rate of active carbon zone,which provides the theoretical basis for the structure design and performance improvement of fuel cell vehicle air filter.
