摘要
依据某地铁车辆车厢中部垂直截面的实际尺寸和布局建立物理模型,对3种送风格栅的车内气流分布从速度场、温度场和压力场方面进行仿真对比分析,确定送风格栅最优类型,以使车内送风均匀性更好,乘客舒适性得到提高。
A physical model is established based on the actual size and layout of the vertical section of the central compartment on metro train,to compare and analyse the airflow distribution in three different air supply grilles,which are simulated in the velocity field,temperature field and pressure field respectively.Then,an optimal scheme of the air supply grille is determined,which chould achieve better air supply uniformity and provide an important theoretical basis for the improvement of passenger′s comfort.
