The suction control of flow separation of a NACA0012 airfoil is studied numerically for Reynolds number Re=104, angle of attack α = 2 ° , 4°, 6°, and 8°, and Re=105, α = 4 ° . The suppression effects of suction are studied considering many parameters such as suction coefficient, location, angle, hole width, and porosity. The variations in energy consumption and lift–drag ratio during the control process are used for evaluating the control effects.
