1. A fluidic oscillator, comprising
an oscillator 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 consists of a fluid pathway from the fluid inlet to the fluid outlet, 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, and
the fluid pathway is defined by the intersection of the first and second fluid interaction regions.
