ABSTRACT:
A system for control of a fluid flow. The system includes an array of fluidic oscillators. Each fluidic oscillator carries an oscillating flow of the fluid and includes a throat, an input port connected to the throat, two control ports connected to the throat and two output ports extending from the throat. A feedback line is connected to each of the two output ports and each of the two control ports. The system further includes a plenum connected to the input ports of the fluidic oscillators to supply the fluid to the fluidic oscillators and a feedback chamber disposed along each feedback line of each fluidic oscillator to provide a feedback path for the control fluid to cause oscillatory fluid motion between the first output port and the second output port, the frequency of which may be modulated by adjusting the volume of the feedback chamber.
