Microfluidic Oscillator

A fluidic oscillator nozzle, comprising

• a nozzle body comprising
• an exterior surface;
• an interior surface defining a three-dimensional space therein;
• a fluid inlet;
• and
• a fluid outlet,
• wherein
• the three-dimensional space, the fluid inlet, and the fluid outlet are in flow communication,
• the three-dimensional space comprises a first fluid interaction region fluidly coupled to a first pair of feedback flow paths, and a second fluid interaction region fluidly coupled to a second pair of feedback flow paths,
• the first and second fluid interaction regions intersect,
• the three-dimensional space comprises a fluid pathway from the fluid inlet to the fluid outlet, the fluid pathway defined by the intersection of the first and second fluid interaction regions, and
• wherein a largest nozzle dimension is less than about 20.0 mm.
