摘要：
The CFD numerical simulation method was used to simulate the wind field of tandem buildings. The influence of the disturbing building height and spacing on the wind energy of disturbed building roof was analyzed，and the roof wind energy was quantitatively compared under single and tandem buildings，so as to obtain the variation law of interference factors in each zone of the roof under different working conditions. The results show that wind energy agglomeration effect is significant under the single building，and the wind energy in each zone changes continuously along the height direction. The maximum wind energy in the upstream and downstream of the roof is located at 1.15H and 1.20H respectively （H is the building height）. In the tandem layout，the wind energy of the disturbed building decrease with the increase of the disturbing building height and spacing，and the wind energy in the upstream center area of the roof is reduced by 67.1%. The change of disturbing building height has a greater impact on interference characteristics than spacing. There is a good linear positive correlation between the interference factors and the characteristic angle in each zone. © 2023 Science Press. All rights reserved.
