Study on Dynamic Stall Control of Rotor Airfoil Based on Coflow Jet
International Journal of Aerospace Engineering, 2020 In this study, a dynamic stall control strategy, called the co-flow jet (CFJ), is applied to the rotor airfoil. The effect of the CFJ on the unsteady dynamic stall characteristics of the rotor airfoil is numerically investigated via numerical simulations
