新能源汽车测试试验室模拟分析与优化

Simulation Analysis and Optimization of New Energy Vehicle Testing Laboratory

新能源汽车在室内进行各项测试时,容易泄漏一些有毒有害污染气体,若未及时净化室内气体,将极大降低检测效率,甚至威胁试验人员生命安全。文章首先从室内采样获取气体排放初始条件;其次,利用ANSYS FLUENT软件组份输运模型,对释放污染气体流动进行瞬态仿真模拟分析,得到污染气体浓度空间分布与变化趋势,对模型结构进行优化,使得模型使用性能提高。

New energy vehicles can produce some toxic and harmful pollutant gases during various indoor tests.Failing to purify indoor gases in time greatly reduces the detection efficiency and even threaten the safety of the experimental personnel.Firstly,initial conditions of gas emissions are obtained by sampling indoors.Secondly,using the ANSYS FLUENT software package's component transport model,transient simulation and analysis of the release of pollutant gases are carried out,to obtain the spatial distribution and trend of the concentration of pollutant gases.The model structure is optimized to improve the performance of the model.
