摘要
为研究幅流风机对公路客车室内热流场的影响。以某12 m长公路客车为研究对象,基于STAR-CCM+进行数值模拟客车在夏季辐射温度36℃时的运行工况。分析有无幅流风机作用下客室内流场和温度场的变化情况。仿真结果表明:加载幅流风机的公路客车会加速室内气流流动,提高流场的均匀度,有利于降低室内温度,增强乘客舒适感。
In order to study the influence of disturbance-flow fan on indoor heat flow field of highway buses, a 12-meter-long road bus was numerically simulated at 36 ℃ radiation temperature in summer based on STAR-CCM+. The flow field and temperature field in the passenger room with or without fan loading were studied. The simulation results show that the highway bus loaded with disturbance-flow fan can accelerate the indoor air flow, improve the uniformity of the flow field, reduce the indoor temperature, and enhance the comfort of passengers.
