Abstract
In this paper, pressure field over the roof of low-rise building model has been investigating using numerical simulations. The model is surrounded by four neighboring buildings of the same geometry as the principle one. The wind behavior around the building was simulated at wind angle of 45 degrees. Numerical calculations are performed using open-source code OpenFOAM. - Analysis solver for incompressible flow was applied using the Large Eddy Simulation (LES). The effect of different mesh types and inflow conditions are discussed. Two inlet definitions was implemented, one without prescribed turbulence, with the stream-wise velocity profile from the wind tunnel (WT), and another with the incoming flow turbulence synthetically generated using the divergence-free synthetic eddy method (DFSEM). Numerical results of pressure distributions statistics are analyzed and systematically compared to the referenced experimental data. The results show that there is a significant influence of the inl...et definition on the mean and standard deviation of the pressure coefficient.
