Abstract
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.
Claims20
An oscillator comprising:
- a base having a cavity with a cross-sectional profile, the 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.
An oscillator base comprising:
- a body extending along a longitudinal axis of the oscillator base, the body including opposing front and rear surfaces arranged across the longitudinal axis, the body including upper and lower surfaces extending between the front and rear surfaces;
- and
- a cavity with a cross-sectional profile at least partially defining an oscillatory chamber, the cavity having an inlet at the lower surface of the body, wherein the cavity is to receive a plunger to vary an aspect ratio of an oscillator associated with the oscillator base.
A method of varying an aspect ratio of an oscillator, the method comprising:
- providing fluid to an inlet of a body of the oscillator, the fluid to exit the body at an outlet of the body as a sweeping fluid jet;
- and
- moving a plunger relative to a cavity of the body to vary the aspect ratio, the cavity defining an oscillatory chamber.
A non-transitory machine readable medium comprising instructions, which when executed, cause a processor to at least:
- determine a desired fluid property of a fluid jet exiting an outlet of a body of an oscillator;
- calculate, based on the desired fluid property, an adjustment of a plunger;
- and
- move the plunger relative to a depth of a cavity of the body to vary an aspect ratio of the oscillator.
