ABSTRACT

The exact analytical solution of the problem, based on the application of the magnetohydrodynamics equations taking into account the surface tension forces, the specific geometry of the magnetic field and the free surface of the magnetic fluid membrane, is a very complicated task. Investigations of the acoustic and hydrodynamic cavitation started with the work of Rayleigh who examined the processes of closure of a spherical cavity in an ideal fluid. In the investigated model, as in the formulation of the Rayleigh problem, no account is made of the effect of surface tension forces and gravitational force. It is necessary to explain the physical nature of factors which determine the processes of rupture and restoration of the orifice and predetermine the numerical values of the parameters. The rupture strength of the fluid is determined by the presence in the fluid of cavitation nuclei and their distribution in the volume.
