This article presents the results of investigations of aerodynamics of two parallel high-rise buildings. The objective of the study the impact of wind on buildings associated with the large-scale design of high-rise buildings, seeking opportunities to use natural ventilation, optimization of air flow inside the building, as well as silicenium heat loss of buildings. Research into the aerodynamics of tall buildings is conducted using the Software Package COMSOL Multiphysics. The study area is constructed in the form of waves of the wind tunnel. Inside the wind tunnel are placed the layout of the two parallel arranged high-rise building. The flow around high-rise building occurs from left to right. The air flow is considered turbulent, non-stationary process. Turbulent motion of the air flow described by the Navier Stokes equations. Modeling of turbulent flow is carried out using the RANS method.The results of calculations performed for various distances between two tall buildings at a fixed air velocity and for different velocities of air flow at a fixed distance between the buildings.
