Abstract :
With the development of urbanization, the wind resource around the building becomes richer. While the atmosphere passes the buildings, there will be a high wind speed in a particular region. This paper is based on Flunet and standard k - ε turbulence model is used to calculate the wind field around a single rectangle building. This paper shows how the inlet speed and the size of the buildings affect the wind speed ratio and turbulent intensity. The biggest wind speed ratio and its position is independent of the inlet speed and the size of the buildings, while the turbulence intensity strengthens with the rising of the inlet speed, weakens with the increasing size of the buildings. Combining with the SN-2000W wind turbine, at its installation height, the turbulence intensity is satisfied while the wind speed reaches the top. In order to prolong the life of the wind turbine and maximize the power, select the place of the highest wind speed to install the wind turbine.
