Wind Characteristics of High-rise Building with Partial Opening

Abstract

Abstract-The paper discusses the wind pressure distributions on high-rice buildings with partial openings by means of wind tunnel tests and numerical simulations. The wind tunnel tests were carried out in the boundary layer wind tunnel over an urban terrain with a geometric scale. The numerical simulations used the method of S IMPLEC algorithm and the turbulence model, in which a realizable κ-ε model was used to simulate the pressure coefficient and the wind environment surrounding the partial openings. Detailed analyses of wind pressure coefficients for buildings of three different opening cases are presented. The results show that the pressure coefficients are different on the two sides of the opening and the distribution of wind velocity surrounding the opening is remarkably affected by the opening size. Moreover, the wind speed reaches the maximum in the opening when the wind direction is 45°. This suggests that there is a potential to utilize the wind energy by placing wind turbines in the partial opening of the high-rise buildings.
