Fluidic oscillator array for synchronized oscillating jet generation

摘要

A fluidic oscillator array includes a plurality of fluidic-oscillator main flow channels. Each main flow channel has an inlet and an outlet. Each main flow channel has first and second control ports disposed at opposing sides thereof, and has a first and a second feedback ports disposed at opposing sides thereof. The feedback ports are located downstream of the control ports with respect to a direction of a fluid flow through the main flow channel. The system also includes a first fluid accumulator in fluid communication with each first control port and each first feedback port, and a second fluid accumulator in fluid communication with each second control port and each second feedback port.

1. A fluidic oscillator array, comprising:
a plurality of fluidic-oscillator main flow channels, each of said main flow channels having an inlet and a single outlet wherein a fluid flow is adapted to enter at said inlet and exit at said outlet, each of said main flow channels having a first control port and a second control port disposed at opposing sides thereof, and each of said main flow channels having a first feedback port and a second feedback port disposed at opposing sides thereof wherein all feedback and control ports on the first side of the main flow channels fluidically communicate with a first feedback accumulator, and all feedback and control ports on a second side of the main flow channels fluidically communicate with a second feedback accumulator; and wherein said first feedback port and said second feedback port are located downstream of said first control port and said second control port, respectively, with respect to a direction of said fluid flow; and wherein the first feedback accumulator is in fluid communication with each said first control port and each said first feedback port; and and wherein the second feedback accumulator is in fluid communication with each said second control port and each said second feedback port.
