ABSTRACT

The secondary cavitational domain of toroidal shape was discovered in operation of axisymmetric hydrodynamic radiator. By estimate of erosional destruction of samples the geometrical parameters of secondary vortex were determined. The intensity of acoustic signal on the boundary of sound generation zone was estimated by two methods using available acoustic and hydrodynamic parameters. Dependence of the sound intensity in the vicinity of the secondary vortex on the excessive static pressure is presented.
