The wind environment around an isolated structure and a group of tall buildings has been attracted more attentionaly in recent years. Recently, people are increasingly concerned about the living environment. Therefore, it is necessary to carry out the systematic study of wind field around the tall buildings. In this paper, the standard k-ε model of turbulence model was adopted to calculate the flow field around the adjacent high-rise buildings. The flow field characteristics of wind speed and air pressure between the two adjacent buildings are analyzed. The impact of the building spacing and other factors on the characteristics of the wind environment was discussed. The results also provided the useful guidelines and references to a certain extent for designing.
