The temperature stratification measurement and simulation in atrium of Wuhan Station

Temperature stratification is obvious in atrium in large space. Firstly we measured the indoor temperature of the atrium and then choose the zero equation turbulence models on the basis of the reasonable physical simplified model. Lastly we simulate the temperature in atrium used CFD software fluent, and the results show that the simulation can be well coincided with the measurement. So we can draw a conclusion that the zero equation models in simulation in large space temperature stratification are practical and at the same time discusses the temperature stratification change rule in large space buildings.
