Oscillatory vorticity generator and applications thereof

摘要

An oscillatory vorticity generator device for controlling the flow on an aero- or hydrodynamic surface of an element, the oscillatory vorticity generator device comprising:
two main walls, positioned opposite to each other, forming a first pair of walls and two other walls, the four walls each having proximal and distal ends, the distal ends connected to an aero- or hydrodynamic surface;a connection connecting the walls at their proximal ends; andan opening in the aero- or hydrodynamic surface, the opening being substantially contiguous with the two main walls and the two other walls.

主权项

1. An element comprising:
at least one aerodynamic or hydrodynamic surface; and at least one oscillatory vorticity generator, wherein the at least one vorticity generator comprises:
four side walls, having proximal and distal ends;a connector connecting the side walls at their proximal ends;wherein the walls and connector form a cavity within the element,wherein the distal ends of the walls are connected to an opening within the aerodynamic or hydrodynamic surface, andwherein two of the four walls are main walls, positioned opposite to each other; andat least one actuator mounted on at least one of the two main walls, such that when activated, the at least one actuator in conjunction with the at least one main wall produces oscillatory pressures within the cavity; wherein the opening in the aerodynamic or hydrodynamic surface is contiguous with the distal ends of the four walls.
