ABSTRACT:
A fluid dispersal device utilizes alternately pulsating vortices to cyclically oscillate a fluid stream transversely of its flow direction in a desired flow pattern. A pair of pulsating fluid streams, which may issue from a fluidic oscillator are projected into an output region or chamber defined in a body member the output region or chamber having inlets for the pulsating fluid streams and at least one outlet opening with the outlet opening being positioned to issue pressurized fluid from the chamber into an ambient atmospher. Vortices formed in the chamber are alternately oppositely rotating and cause the flow pattern to cyclically sweep across the outlet. The vortices have axes normal to the direction of fluid flow and alternately spin in first and second directions in response to inflowing of the first and second pulsating fluid streams to the chamber and the output flow is cyclically swept back and forth as each vortex spins in the first and second directions respectively.
