Abstract: Turbulent flow around a circular cylinder with a perforated housing, when a stagnation zone flow at the forward stagnation point is transported to the near-wake region during wind energy extraction, was studied numerically using the multiblock computational technologies of solution of the Reynolds equations closed by the equations of the shear stress transfer model. It turned out that the energy extraction promoted an additional drag reduction of the energy-efficient building model under consideration.
