Direct Numerical Simulations of a rotating airfoil at Re=100,000, several angles of attack, and rotation speeds were performed. Rotation increased the reversal flow during separation and postponed the reattachment and transition. Lift was reduced, and drag was increased by rotation. Higher angles of attack and stronger separation enhanced the rotation effects.
