Numerical simulation and evaluation of wind environment about square earth buildings

Square Tulou as the typical of Fujian province. Based on Computational Fluid Dynamics (CFD) software CFX and the SST k-ω) turbulence physics model, this article simulate the wind environment of tulou under different Wind incidence direction, In order to more accurately predict tulou wind environment. To be pedestrian height of the wind speed separation in the corner, where the formation of similar to the "horseshoe" area of strong wind, the wind speed increased by nearly 0.7 times. As a result, pedestrian courtyard height of the flow field has changed, where the average wind speed ratio decreases. Tulou courtyard played an important role in the heat exchange, which between environmental qualiy and the air inside the building heat. The wind speed and flow of various regions inside and outside the building comprehensively deduced by numerical simulation can be provided as a basis for the assessment of wind environment.
