某乘用车的乘员舱热舒适性分析与研究
|
摘要
采用三维软件UG对某车企轿车进行参数建模,运用ICEM建立体网格,利用Fluent软件计算其流体动力学,应用Realizableκ-ε湍流模型对乘员舱热舒适性进行了数值计算,重点讨论了在各种不同的工况下对车厢内温度场和速度场的影响,为指导汽车乘员舱的热舒适性设计分析提供依据。
Three-dimensional software UG was used to model the parameters of a car-enterprise car,ICEM was used to built the body mesh,Fluent was used to calculate its fluid dynamics, and the thermal comfort of the cabin was calculated by using a Realizable κ-εturbulence model. The influence of different working conditions on the temperature field and velocity field was discussed. The study can provide the basis for guiding the design and analysis of thermal comfort of the passenger cabin.
