Simulation of the Wind Effect on an Ensemble of High-Rise Buildings by means of Multiblock Computational Technologies

The numerical simulation of the wind effect on an ensemble of high-rise buildings is based on the solution of Reynolds-averaged Navier–Stokes equations closed with the help of a shear stress transfer model modified with account for the influence of the curvature of streamlines with the use of multiblock computational technologies in the VP2/3 package. It has been shown that the nonstationary aerodynamics of construction ensembles of closely spaced high-rise buildings has the characteristic features inherent in tandems of blunt bodies, and the pulsating loads in the lee buildings are largely determined by the self-organization of the jet-vortex structures in the space between buildings.
