Abstract

Abstract

The dynamic stall process in three-dimensional (3D) case on a rectangular wing undergoing a constant rate ramp-up motion was introduced to provide qualitative analysis about the onset and development of the phenomenon of the stall.Subsequently,on the base of having enhanced the understanding of the mechanism of the dynamic stall,a 3D dynamic stall model was constructed with the emphasis of the onset,growth and the convection of dynamic stall vortex on the 3D wing surface.The results show that this engineering dynamic stall model can simulate the 3D unsteady aerodynamic performance appropriately.
