轿车室内流场的数值模拟是轿车室内环境空气品质评价与研究的基础。本文选择RNGk?ε湍流模型,采用分区域划分网格的方法,并利用MonteCarlo法分析了太阳辐射引起的车体各固面的附加热流变化,对轿车室内空气三维流场和温度场进行了数值模拟研究,为轿车室内环境的舒适性评价和轿车室内通风性能的优化提供了参考。
The numerical simulation of the flow field in a car interior is the basis for the evaluation and research on the indoor ambient air quality of a car. In this paper, the RNGk? Turbulence model is selected, the method of dividing the grid by subarea is adopted, and the additional heat flux of each solid surface caused by solar radiation is analyzed by Monte Carlo method. The three-dimensional flow field and temperature field of car indoor air are numerically The simulation study provides a reference for the comfort evaluation of the indoor environment of the car and the optimization of the indoor ventilation performance of the car.
