Numerical Simulation of Flow around High-Rise Buildings Based on Reynolds Stress Model

Abstract:

In this paper, a modified inlet atmosphere boundary layer (ABL) which satisfies the turbulence model equations is applied to computational wind engineering. The new inflow turbulence boundary condition applied to simulating the flow in the cavity is verified that it is more in line with the actual flows, and then it is used to establish the numerical wind tunnel model to simulate the flow around high-rise buildings. The results are in good agreement with the wind tunnel experimental data, which show the modified ABL combined with Reynolds Stress Model (RSM) is able to better simulate the flow around high-rise buildings.
