摘要:
通过利用多孔介质一维“多孔跳跃”模型和标准k-ε方程模型相结合的方式，研究车辆客室顶部侧送格栅风口送风角度、顶部侧送格栅风口位置及送风口风速。通过仿真模拟，比较分析典型截面处的热舒适性指标PMV（预测平均热感觉）和PPD（预测不满意百分率）。结论为：车辆客室上部格栅侧送风口建议采用与车辆客室上部格栅顶送风口错开的布置方式，格栅方向与列车地板水平面成45°夹角，风口风速为1 m/s。
Abstracts:
By using combination of the porous media one-dimensional "porous jump" model and the standard k-ε equation models, the airflow angle of the top side grille air outlet, the position of the top side grille air outlet and the air speed at the air outlet in the passenger compartment were studied. Through simulation, comparative analysis of thermal comfort index PMV (predicted mean vote) and PPD (predicted percentage dissatisfied) at a typical section were conducted. The conclusion is that the air outlet on the upper grille side of the passenger compartment is recommended to be staggered from the air outlet on the top grille of the passenger compartment. The direction of the grille is at an angle of 45 ° to the train floor horizontal plane, and the air velocity of the air outlet is 1 m/s.
