Numerical Study of Atmospheric Air Flow in the Vicinity of Urban Environment

The article is devoted to the numerical simulation of turbulent air flows in the vicinity of building complexes. The simulation was performed under isothermal assumption on the basis of 3D URANS equations supplemented with the k-omega SST turbulence model. The ANSYS Fluent Software was used as the main modeling tool. the atmospheric flow in the neighborhood of a building of a complex shape was carried out taking into account the surrounding objects. The numerical simulation was performed under the conditions of the experiments. The 3D structure of the flow in the vicinity of the building was obtained and the comparison of the calculation results with the experimental data on the pressure coefficient distribution on the walls of the building was performed.
