基于SST k-ω湍流模型的平衡大气边界层模拟
Simulation of equilibrium atmosphere boundary layer with SST k-ω turbulence model
摘要
Abstract
To achieve the equilibrium atmosphere boundary layer in an empty flow field with SST k-w turbulence model, the method of adding source terms to the turbulent kinetic energy transport equation and the specific dissipation rate transport equation respectively was adopted to make the inlet profiles of average wind and turbulence wind consistent with the turbulence model, the consistency of the average wind profiles, turbulent kinetic energy profiles and specific dissipation rate profiles at several different positions with and with-out considering the source terms were investigated respectively according to the corresponding CFD numerical example. The numerical result shows that when considering the source terms in the turbulence model, the average wind profiles, turbulent kinetic energy profiles and specific dissipation rate profiles at several different positions along the flow field are all maintained very well, which indicates that the equilibrium atmosphere boundary layer in the empty flow field is achieved satisfactorily. The study conclusion proposes a new idea or research method for modeling the equilibrium atmosphere boundary layer and also provides the further CFD simulations in structural wind engineering with theoretical and actual values.关键词
