In order to study the thermal comfort experience status of passengers under natural ventilation conditions at elevated subway stations in subtropical monsoon area and improve the level of subway service,a side and island elevated subway station in Changsha City was selected as the object,and the thermal environment was measured at the platform floor during the hottest period of a typical summer day,and the thermal environment distribution was analyzed according to the calculation results.Based on measurements of wind speed,temperature,and other data,the computational hydrodynamics software,Fluent,was used to simulate the variability of the wind speed and temperature fields at the side and island elevated stations in this climate.The mean values of the wind speed and temperature at 1.5 m were extracted and the relative thermal index(RWI)was used to assess the thermal comfort of the platform layer.The results showed that the measured thermal environment met the indoor air quality standards,except for the temperature and wind speed.Under the same outdoor meteorological conditions,wind speed and temperature field variations are significantly different on the side platform and the island platform,and the thermal comfort experience on the island platform is similar to that of the side platform.
