Abstract: Original multi-block computational technologies based on the use of different-scale overlapping grids and implemented in the VP2/3 package are used to numerically simulate the effect of wind shear on a two-dimensional turbulent flow around an energy-efficient high-rise structure. The structure is a circular cylinder in a perforated casing. The throttling effect associated with the bypassing of air from the braking zone in front of the body to the area of the near wake behind it stabilizes the flow around the body and reduces its drag. The wind shear is simulated by a vortex street behind the transverse smallsize square cylinder placed in front of the body. As a test, we consider Igarashi's experiment on the interaction of a vortex street behind a small-diameter cylinder with a transverse plate in a uniform air flow.
Keywords: wind shear, turbulence, cylinder with perforated casing, plate, vortex street, multi-block computing technologies.
