ABSTRACT

A model of axially symmetric hydrodynamic acoustic sound sources of a direct-flow design (with a circular nozzle and stepwise obstacle) and counter-flow one is considered. The basic frequency of acoustic signal is calculated as a function of working fluid properties, geometric and hydrodynamic parameters of the jet. The numerical data are compared with experimental results. A criterion of conformity of the model with real sound sources of considered types is proposed.
