Simulation of aerodynamic characteristics of high-rise buildings

In the article, based on the analysis of meteorological data, the vertical profile of the estimated wind speed in modern high-rise buildings is refined and, in this regard, the aerodynamic characteristics of high-rise buildings are studied. The regularity of the airflow around high-rise buildings is considered and the regularities of the distribution of wind pressure over the surface of the walls of buildings depending on their geometric dimensions are established. The aerodynamic characteristics of buildings are studied, the distribution of air flow on the surfaces of the walls is determined, which determine the vertical profile of the velocity pressures of the buildings under consideration, which is taken into account when calculating the strength and stability of the structural system, the connection points of the structures of facade systems, the strength of the translucent structures of high-rise buildings and the organization of natural air exchange between the premises and the external environment. The spectrum of aerodynamic coefficients on the windward, leeward and sidewalls of a high-rise building is determined, which makes it possible to predict the value of wind pressure on walls of different orientations in relation to the oncoming airflow. The results of experimental modeling aerodynamic studies can serve to improve engineering methods for calculating the aerodynamic characteristics of high-rise buildings, which is a factor of reliability, safety and comfort.
