OPTIMIZATION OF THE SLOT SUCTION OF AIR FROM A CIRCULAR VORTEX CELL ON A THICK NACA0022 AIRFOIL WITH A MAXIMUM LIFT–DRAG RATIO



On the basis of multiblock computational technologies and the Menter model of shear-stress transfer modifi ed with account of the curvature of streamlines, the optimum position of a slot for air suction on the leeward side of the contour of a vortex cell built in a thick NACA0022 airfoil was determined for the purpose of increasing its lift–drag ratio to a maximum value in a nondisturbed air fl ow at a Mach number of 0.05 and an angle of attack of 7o .
