【 摘 要 】

With the improvement of computer performance and the gradual maturity of the computational methods, numerical wind tunnel in the simulation based on computational fluid dynamics has been developed rapidly and turned into one of the hottest investigated topics in computational wind engineering. Simulation method of turbulence, inflow turbulence generator method and the size of the grid scale are mainly included in the influence factors of the wind-induced response around the building in the computational domain. The above influence was analysed and summarized. The results show that the numerical wind tunnel in the simulation has made some good progress, but there are still a lot of contents that need to be further studied.
