The research presents a numerical simulation of the flow around buildings. The authors carried out a numerical simulation using a computational fluid dynamics tool called OpenFOAM. The Reynolds-averaged Navier–Stokes equations were solved using a two-parameter turbulence model. The results obtained through numerical simulations are further processed with ParaView software, which is based on a visualization toolkit. The flow’s impact on buildings is described in terms of velocity contours. Additionally, the same data is processed using linear integral convolution to reveal the three-dimensional properties of the flow in a plane parallel to the incoming stream. The images generated through visualization confirm the actual wind flow across the city. The research aims to model the aerodynamics of an urban development model. The mathematical model of the considered problem is based on the Reynolds-averaged Navier–Stokes equations. The computational domain was discretized using the OpenFOAM package and the BlockMesh utility, with equation discretization performed using the finite volume method. The authors modeled the aerodynamics of urban buildings by numerical methods within the framework of the OpenFOAM package. The Reynolds-averaged Navier–Stokes equations were solved together with a two-parameter turbulence model. The results of the simulations were further processed with ParaView software. Parameters such as wind pressure and velocity in various planes were modeled, aligning well with experimental data.
