| 摘 要： | 针对高速列车的车厢内温度场和流场进行CFD模拟分析,对车内热舒适性做出评价。本文计算得出列车车厢在4500m3/h的送风量和18℃的送风温度下,车厢内的平均温度约为24.9℃,PMV值介于0~1.0,车厢内的热环境为中等舒适状态。车厢内的空气龄较小,乘客区气流分布较为合理。部分区域,如行李架和车厢后部,存在温度偏高和空气龄较大的现象。

| Abstract: | The temperature and flow field in the compartment on the high-speed train was simulated by the software of CFD in this paper,and in which the thermal comfortableness was evaluated.It was calculated that the average temperature of the compartment was about 24.9℃ and the PMV value was between 0 with 1.0,when the air supply volume was 4500m3/h and the air supply temperature was 18℃.The thermal environment in carriage was in the state of a little hot.Age of air in the compartment was relatively small,and the air distribution of passengers area was much reasonable.But the temperature and age of air were higher in some areas,such as luggage carrier and the rear of the compartment. |
