摘要： A fluidic oscillator having independent frequency and amplitude control includes a fluidic-oscillator main flow channel having a main flow inlet, a main flow outlet, and first and second control ports disposed at opposing sides thereof. A fluidic-oscillator controller has an inlet and outlet. A volume defined by the main flow channel is greater than the volume defined by the controller. A flow diverter coupled to the outlet of the controller defines a first fluid flow path from the controller's outlet to the first control port and defines a second fluid flow path from the controller's outlet to the second control port.

摘要： A fluidic oscillator can include an input, first and second outputs on opposite sides of a longitudinal axis of the oscillator, whereby a majority of fluid which flows through the oscillator exits the oscillator alternately via the first and second outputs, first and second paths from the input to the respective first and second outputs, and wherein the first and second paths cross each other between the input and the respective first and second outputs. Another oscillator can include an input, first and second outputs, whereby a majority of fluid flowing through the fluidic oscillator exits the oscillator alternately via the first and second outputs, first and second paths from the input to the respective first and second outputs, and a feedback path which intersects the first path, whereby reduced pressure in the feedback path influences the majority of fluid to flow via the second path.

摘要： A device includes a fluid flow channel having a channel inlet for receiving a pressurized fluid for flow through the fluid flow channel and a channel outlet for discharging the pressurized fluid therefrom. A passive flow element is situated within the fluid flow channel or proximate to the channel inlet. The passive flow element includes an element inlet for receiving the pressurized fluid, and an element outlet. The passive flow element also includes a cavity for receiving the pressurized fluid from the element inlet and generating a periodic flow variation of the pressurized fluid so as to modulate the pressurized fluid flow rate through the element outlet.
