Abstract

Abstract: The original multiunit computational technologies based on the use of different-scale intersecting grids and implemented in the VP2/3 package are applied 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 related to the bypass 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 the vortex street behind the transverse small square-section of a 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.
