ABSTRACT:
In accordance with an illutrative embodiment of the present invention, a fluidic oscillator includes a transverse vacuum port which extends between the diffuser legs a predetermined distance below the leading edge surface of the splitter. When flow is down one leg, a slight negative pressure condition is created in the port and transmitted thereby to the other leg, which causes switching of the flow to such other leg. The process then repeats in response to negative pressure in the one leg to cause switching of the flow back thereto. Fluid flow thus is switched back and forth between the legs at a resonant frequency, so that continuously fluctuating pressures are applied to the surrounding medium.
