利用STAR-CCM+软件对某型轿车的乘员舱进行数值模拟,计算中考虑到太阳辐射和壁面间辐射的影响,设定太阳的方位角和高度角均为90?,通过仿真得到舱内速度场、温度场以及人体表面温度的分布;通过建立PMV-PPD指标评价乘员舱的整体热舒适性,再利用EQT指标评价舱内乘员的局部热舒适性,利用多指标评价体系较为全面地评价乘员舱内的热舒适状况。
The STAR-CCM + software was used to simulate the crew cabin of a car. Considering the influence of solar radiation and the radiation between the walls, the azimuth and elevation angle of the sun were set as 90 °. The velocity field in the cabin was obtained by simulation , The temperature field and the distribution of body surface temperature. The PMV-PPD index is used to evaluate the overall thermal comfort of the passenger compartment, then the EQT index is used to evaluate the local thermal comfort of the cabin occupants. The multi-index evaluation system is used to evaluate the passenger compartment Inside the thermal comfort.
