Abstract
A method and device for creating a distribution of unsteady suction, the device may include ejectors; and a fluidic oscillator; wherein the fluidic oscillator may be configured to switch a first flow of fluid, in a cyclic manner, between the ejectors; wherein the ejectors may be fluidly coupled to the fluidic oscillator; and wherein each one of the ejectors may be configured to create pulsed suction through at least one first aperture, and (b) pulsed ejection through at least one second aperture.
Claims20
A method for creating a distribution of unsteady suction, the method comprises:
- switching a first flow of fluid, in a cyclic manner and by a fluidic oscillator, between ejectors that are fluidly coupled to the fluidic oscillator being downstream of said fluidic oscillator;
- and forming the distribution of unsteady suction at an aerodynamic surface that is fluidly coupled to the ejectors, by creating, by each one of the ejectors, (a) pulsed suction through at least one first aperture downstream of said fluidic oscillator, and (b) pulsed blowing through at least one second aperture.
A device for creating a distribution of unsteady suction, the device comprises:
- a fluidic oscillator and ejectors located downstream of the fluidic oscillator;
- wherein the fluidic oscillator is configured to switch a first flow of fluid, in a cyclic manner, between the ejectors;
- wherein the ejectors are fluidly coupled to the fluidic oscillator;
- and wherein each one of the ejectors is configured to create (a) pulsed suction through at least one first aperture downstream of said fluidic oscillator, and (b) pulsed blowing through at least one second aperture.
