Parameter-Based Design and Analysis of Wind Turbine Airfoils with Conformal Slot Co-Flow Jet [PDF]
Journal of Applied Fluid Mechanics, 2022 A co-flow jet (CFJ), an active flow control method combining blowing and suction control, can effectively suppress the stall of airfoils. However, the streamwise jet channel along the upper surface of a conventional CFJ airfoil reduces the thickness and ...
