ABSTRACT

A toroidal secondary cavitational domain occurring at operation of the uniflow hydrodynamic sound source with a circular nozzle and stepwise barrier is studied. Geometrical parameters of the secondary vortex were determined by erosional destruction of the model contamination. We calculate the field intensity in the vicinity of sound production zone using acoustic signal parameters. The dependencies of elastic wave intensity and the specific power for period of oscillations on the functions of static pressure in the fluid are presented.
