Adjustable fluidic oscillators are disclosed. A disclosed example oscillator includes a base having a cavity with a cross-sectional profile defining an oscillatory chamber between an inlet and an outlet of the oscillator, and a plunger to be received by the cavity and movable along a depth of the cavity to vary an aspect ratio of the oscillator.

The disclosure describes a fluidic oscillator. The fluidic oscillator is configured to oscillate between a closed state and an open state. The fluidic oscillator comprises an oscillator conduit forming an oscillator chamber comprising an inlet and an outlet wherein the inlet and the outlet are configured to enable fluid flow through the oscillator chamber. An inner chamber of the oscillator chamber further includes a flexible element wherein a rate of fluid flow through the oscillator chamber results in a deformation in the flexible element. In other elements, the fluid oscillator further comprises two fluidic gates comprising a deformable chamber wherein changes in a control pressure of a control fluid in the deformable chamber results in a deformation in a volume of the oscillation chamber.
