Design and experimental study of fluidic micro-oscillator

A fluidic oscillator consisting of a bistable fluidic element and two chambers is proposed. Each outlet of the fluidic element is connected with a chamber and feeds back to control channel. Experimental data with various survey pressure illustrate that the main parameters influencing the oscillating frequency, such as the supply air pressure, the length of feedback pipeline and the volume of the oscillating chamber. The working principle of the oscillator is analysed and provides experimental and theoretical evidence for its using.
