A study on the vortex oscillator. II  Oscillatory phenomena occurring in a confined vortex oscillator
Abstract
A vortex oscillator, which has a double input vortex chamber and two conduitcapacity systems, is studied theoretically and experimentally. An oscillator with a single conduitcapacity system is also examined. A mathematical model of this type of oscillator is presented and its validity is examined by experiments. The stability of the equilibrium state of the system is discussed. Higher modes of oscillation occur in the system under certain conditions when the compressibility of the working fluid is relatively large. The frequency of the higher mode coincides with the natural frequency of the same mode of the conduitcapacity system of the oscillator. Relaxation oscillations occur under certain conditions also. The experimental data were found to be in good agreement with theoretical predictions.
