A Study on a Fluidic Oscillator with Feedback Tubes : Nonmemory Bistable Fluid Amplifier Oscillator

Abstract

In this report is studied a fluidic oscillator, made of a nonmemory bistable amplifier, with loads and feedback tubes. A mathematical model for describing approximately the performance of the oscillator is presented. Analytical results derived from the model are examined by experiments. The results obtained are summarized as follows : (1) The model explains the performance of the oscillator fairly well. And the relation between performance and geometry of the oscillator is clarified. (2) Analytical results concerning the condition for sustained oscillation and the frequency of the oscillation show good agreement with experimental data.
