Numerical simulation of mean interference effects for the interfering buildings with different heights

The mean wind-induced interference effects between two high-rise buildings, in which the interfering buildings have different heights, were numerical simulated in the terrain roughness of B and D types by the Reynolds stress equation model（RSM） of fluent. The results are in good agreement with those of the wind tunnel test. Influences of the relative arrangement of two buildings, the height of the interfering buildings and the terrain roughness upon the mean interference effects were analyzed, and the space distributions of IFcp^s on the principal building under tandem arrangement were studied. The results indicate that the lower interfering buildings can always bring larger interference factors comparing to the higher ones under tandem arrangement except that the height is larger than 1.25h, and the heights＇influence on the mean interference effects will increase as the reduced spacing of two buildings. The influence of heights will be little under stagger arrangement.
