Abstract On the basis of the solution by multi-block computational technologies of Reynolds equations closed with the aid of the equations of the model of Menter’s shear stresses transfer, an analysis of the flow around a thick airfoil of classical geometry with vortex cells is given at an arrangement of suction from the surface of central bodies placed inside them. The suction velocities, angles of attack, and location of vortex cells on the contour are determined, under which the flow around an airfoil of 35,2% thickness is ensured close to a separation-free flow, for high Reynolds numbers (Re = 105). The integral force characteristics of the Goettingen and EKIP profiles are compared for the distributed and concentrated suction in vortex cells.
