Optimized Global Resolvent Analysis to Improve Plasma Actuator Control over the Airfoil Surface

What is it about?

The study inspect the effects of the plasma actutor on the flow instablities above the airfoil surface through the globle resovent analysis method. Through the optimal input and output modes from the resolvent analysis, the airfoil performance could be improve by enhancing the flow structure with favourable Reynolds shear stress components. The accuracy of the resolvent analysis was improved by the optmial alignment between the resolvent response mode and the SPOD mode from the previous study.
