초록

An active perturbation-producing element on the solid surface is driven to induce oscillations in the boundary layer of the fluid stream about an axis substantially perpendicular to the solid surface, to enhance the mixing of the boundary layer in the fluid stream. The method is particularly applicable for increasing the lift of a wing, but may also be used for increasing the divergence angle of a diffuser.

청구항

An active method of delaying the separation of the flow from a solid surface to higher angles of divergence or incidence characterized in that a perturbation-producing element on the solid surface is driven by an active drive at a predetermined frequency dependent on the air stream velocity but independent of the fluctuations existing locally in the flow, to induce travelling oscillations in the boundary layer of the fluid stream substantially perpendicular to the solid surface to enhance mixing of the boundary layer with the fluid stream outside the bou...
