Patent ID: 7055541

Claim:
A method of producing a suction and periodic excitation flow, the method comprising: (a) providing a flow of a fluid from a jet port characterized by a first diameter (d1) at a controlled input pressure (Pin); (b) directing said flow to a conduit characterized by a second diameter (d2) wherein d2 is greater than d1; (c) allowing additional fluid to join said flow through at least one suction slot to create an amplified flow; said at least one suction slot in fluid communication with said conduit; (d) further directing said amplified flow in a first desired exit direction by applying a transverse pressure differential to a longitudinal axis of said flow; (e) further redirecting said amplified flow in at least one additional desired exit direction by modifying a circumferential angle by which said transverse pressure differential is applied to said longitudinal axis; and (f) iteratively repeating said further directing and further redirecting so that said amplified flow oscillates between said first desired exit direction and each of said at least one additional desired exit direction.
