Fluidic Oscillator Having Decoupled Frequency and Amplitude Control

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.

1. A fluidic oscillator having independent frequency and amplitude control, comprising:
a fluidic-oscillator main flow channel having a main flow inlet and a main flow outlet, said main flow channel having a first control port and a second control port disposed at opposing sides thereof, said main flow channel defining a first volume between said main flow inlet and said main flow outlet; a fluidic-oscillator controller having an inlet and outlet wherein a second volume is defined between said inlet and said outlet, and wherein said first volume is greater than said second volume; and a flow diverter coupled to said outlet of said controller, said flow diverter defining a first fluid flow path from said outlet to said first control port and defining a second fluid flow path from said outlet to said second control port.
