| The secondary cavitational domain of thoroidal shape was discovered at operation of axisymmetric hydrodynamical radiator. By estimate of erosion destruction of samples the geometry parameters of the secondary vortex were determined. After available acoustic and hydrodynamical parameters by two methodics the intensity of acousticsignal on the boundary of sound-production zone was calculated. Dependence of the sound intensity in the vicinity of the secondary vortex from the excess static pressure is presented. |
