Geometric optimization of the aerodynamics of a high-rise building with a built-in wind generator

This article examines the influence of changes in building geometry on wind flow in the working area of wind generators. Air flows are an alternative source of energy, and the geometry of the surrounding forms directly affects the efficiency of wind generators, the integration of which into the body of a building has recently become popular. The research used numerical modeling of a building in the Ansys CFX software package. The geometric dependence of the length of the facade on other building parameters was derived. Six building forms with the same floor plan area were considered. For a more objective assessment, the study was carried out using different angles of attack of the wind flow. To select the optimal geometric shape, a coefficient was used that showed the change in air velocity inside the wind generator relative to the original shape. The optimal form is with a slight slope of the facade. This shape allows the direction of the air flow into the wind generator at a fairly high speed and from almost any wind direction.
