Abstract

The paper considers dynamic stall of aerofoils and, in particular, the duration of the stall once it has been initiated. The stalling process is likened to a transition from a streamlined flow to that of a bluff body where the flow development is governed by the mean flow. It is concluded that the present data favours this transition occurring soon after stall onset and, because of this, there are constant non-dimensional time delays associated with the process; independent of reduced frequency/pitch rate and aerofoil shape etc.
