Abstract
Moving surface separation control problem is being numerically investigated for a NAC A 0012 airfoil at 20° angle of attack. Here slip velocity is imposed on the portions of top and bottom surface of the airfoil to simulate the experiments of Modi et al [1] where rotating cylindrical portion at the leading edge of the airfoil exercised the control. We have studied the problem for Re = 3000, 35000 and 46200 by solving the unsteady 2D Navier- Stokes equation that utilises an orthogonal grid and higher order upwinding scheme for the nonlinear convection terms.
