Wind environment around building complex under different wind directions

High-rise and high-density building complex is one of typical characteristics of modern urban development. The unique micro-environment formed inside the building complex, especially pedestrian height, directly affects the living quality of dwellers. Hence evaluating the wind comfort at pedestrian height and analyzing the formation of wind environment are the significant research fields of building complex wind environment. Measures and simulates the wind environment at the pedestrian height of the dormitory group of Tongji University in Zhangwu road using the standard K-ε turbulent model, and analyses the building complex wind environment based on the wind comfort theory. The results indicate that when the overall orientation of the building complex is consistent with the direction of the wind, a high-quality building complex wind environment can be achieved, but the Venturi effect of the street canyon makes it difficult to ensure the wind comfort of local environment of the building complex.
