Fluidic Oscillator Array for Synchronized Oscillating Jet Generation

A multi-layer fluidic oscillator array, comprising:

• a first layer defining a plurality of fluidic-oscillator main flow channels, each of said main flow channels having an inlet and an 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 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;
• a second layer defining a first feedback accumulator in fluid communication with each said first control port and each said first feedback port;
• a third layer defining a second feedback accumulator in fluid communication with each said second control port and each said second feedback port;
• a first set of coupling channels formed between said first layer and said second layer for placing said first feedback accumulator in fluid communication with each said first control port and each said first feedback port;
• and
• a second set of coupling channels formed between said first layer and said third layer for placing said second feedback accumulator in fluid communication with each said first control port and each said first feedback port.
