Dynamic Stall

Dynamic stall is a topic of great interest in unsteady flows since it can lead to aerodynamic forces and moments severe enough to cause catastrophic structural failure. Onset of dynamic stall is of particular interest as that is the point where it is easiest to control. We are working on characterizing stall onset with the aim of developing a universal parameter that can indicate stall-onset and can be used to trigger stall control measures.
