| 摘 要： | 基于计算流体动力学对某列车车厢内部的速度场与温度场的分布进行了数值模拟。采用稳态不可压缩雷诺平均N-S方程,紊流模型选择两方程模型,应用有限体积法计算了车厢内气固耦合传热问题。研究了送风方式和送风速度对空调列车室内流场的影响,以及送风温度对列车室内温度场的影响,为空调列车室内气流组织优化设计及舒适性研究提供依据。

| Abstract: | The airflow field and temperature distribution in one carriage are numerically simulated based on computational fluid dynamics(CFD).The steady state incompressible Reynolds-average Navier-Stokes equations and k-turbulence model are used for the airflow model and the fluid-solid coupling heat transfer problem is resolved by finite volume method.The effect of air supply mode and air supply velocity on the airflow field,and the effect of air supply thermal on the temperature field are researched into.It provid... |
