During dynamic stall, large peaks in lift, pitching moment and drag appear, and these cause an undesirable increase in the mean drag. Dynamic stall can also lead to potentially fatal structural loads due to strong vibrations of flexible aerodynamic surfaces. Despite extensive analytical, numerical, and experimental efforts to study dynamic stall, progress is needed for the full understanding and prediction of the relevant complex fluid dynamic mechanisms.
