摘要
通过有无加载幅流风机和调整空调出风温度,设计了三种不同工况,建立了1∶1的实车模型和人体模型,借助计算流体动力学(CFD)数值模拟方法,研究了满载情况下地铁车厢乘客的热舒适性。研究发现,幅流风机对满载地铁车厢的舒适性具有一定的改善作用,同时亦需综合考虑送风温度等多种因素使乘客舒适度达到最优。
In this article,by setting the cross-flow fan and adjusting the temperature of the air outlet,three different conditions are designed,a real1∶1car model and human body model is built,the passenger comfort on a full load metro train is studied with CFD(computational fluid dynamics)simulation method.The results show that the cross-flow fan can improve passenger comfort on a full load metro train to a certain extent,but other factors such as the outlet air temperature should also be put into consideration in order to achieve the optimal comfort.
