列车厢内空调效果的测定

Prediction the Air-conditioning Effect of the Train

采用k -ε模型和SIMPLE算法对硬卧列车空调设计工况下的气流分布进行数值计算。并实验实测车厢内的速度、温度分布。截取断面进行流场、温度场以及特征断面的PMV值的分析 。

In the paper,the velocity and temperature distrbution in the sleeping berth of the train are obtained based on the classical computational stimulation method:k-ε turbulent model and SIMPLE code on PHOENICES platform.Moreover,experiments on spot are made to compare and evaluate the numerical results.The air distribution of representative scction and the PMV values of the specific section on various levels are analyzed in detail.So reference on the effect of the air conditioning in the train can be available at last.
