Dynamic Stall Control on the Wind Turbine Airfoil via a Co-Flow Jet
Energies, 2016 Dynamic stall control of a S809 airfoil is numerically investigated by implementing a co-flow jet (CFJ). The numerical methods of the solver are validated by comparing results with the baseline experiment as well as a NACA 6415-based CFJ experiment ...

Modeling the interplay between the shear layer and leading edge suction during dynamic stall
The Physics of Fluids, 2019 The dynamic stall development on a pitching airfoil at Re = 106 was investigated by time-resolved surface pressure and velocity field measurements. Two stages were identified in the dynamic stall development based on the shear layer evolution.
