Experimental Study of Self-Oscillations Developing in a Swirling-Jet Flow
Abstract
The results of an experimental investigation of the periodic pressure oscillations developing in a submerged swirling jet flowing out into an open space are presented. The main governing parameters of the process are determined and a general dependence relating the oscillation frequency with the governing parameters over a wide range of parameter variation is established experimentally. On the basis of this dependence, an empirical formula for calculating the oscillation frequency is proposed.
