摘要

本文针对非屏蔽门系统地铁站台典型气流组织，建立了站台活塞风与空调射流非等温合温度场理论数学模型，推导出非等温耦合射流质量平均温度和轴心温度的动态变化特性：两者随着列车进站动态过程在相同水平位移处均呈现温度值先逐渐降低（10~30 s）、保持最低值（40~70 s）和后面逐渐升高（80~105 s）的变化特点，且两股射流非等温耦合的轴心温度略低于质量平均温度。通过液体缩尺模型实验对这两股射流非等温耦合温度场理论模型进行了验证，实验结果与耦合射流轴心温度理论计算值的最大误差均在5%以内。

Abstract

As to the typical air-distributions in subway platforms without screen doors

the temperature mathematical model of non-isothermal coupling airflows between the platform piston wind and air-conditioning jet is established. The dynamic natures of the mass average temperature and the axial temperature of the two coupling airflows are deduced. Both of them at some horizontal offset decrease at first(10-30 s)

keep minimal value(40-70 s)

and increase gradually later with train-in dynamic process(80-105 s). And the axial temperatures of the coupling airflows are lower than their mass average temperatures. Compared with the experimental results of the liquid scale model test

the maximum error between the theoretical value and the test results are within 5%. This is a good validation to support the correctness of the theory model.
