Abstract: | Problems of the numerical simulation of the air flow past buildings and structures are considered using the closed vortex loop method. A mathematical model, based on the vortex approach, of the time-dependent ideal incompressible fluid flow past a system of bodies is proposed. A numerical scheme for solving the problem and an algorithm for calculating the distributed wind loads over the body surface are outlined. An example of calculating the aerodynamic loads is given for a real building and the results are compared with the known results of testing a model of the building in a wind tunnel. An example of the calculation and analysis of the wind distribution over a system of several buildings is also presented. |
