Study of wind environment around building complex based on CFD

Numerical simulation is carried out to investigate the wind environment around a single building and a building complex based on and the Reynolds averaged N-S equations and the RNG k-e turbulence model.In the simulation,the computational domain was divided into tetrahedral elements with good adaptability and the finite-volume method was used for numerical discretization of the governing differential equations.The flow field was numerically solved by means of CFD software Fluent.In general,the numerical results using the RNG k-e turbulence model agree well with the previous wind speed ratio of the wind tunnel results in the area behind building,but the numerical results are overestimate near the corner.
