We consider the major cases of local electrification of bubbles in a cavitation field: the fragmentation of cavitation bubbles and also their deformation only. We consider the splitting of cavitation bubbles taking into account the force of surface tension, the force of bubble perturbation, the Stokes force and electrostatic forces of repulsion between like charges on the wall of the collapsing neck of the fragment bubble. The problem of the uncompensated charge on the surface of the deformed cavitation bubble is solved in general view. Radial deformations are approximated by a paraboloid of rotation. The maximum electric strength is calculated. In terms of the electrical theory of the local electrification of cavitation bubbles an explanation of some physical and physico-chemical effects in cavitation fields is proposed.

    Bubble collapse is an effective mechanism for the concentration of the diffuse energy of a sound field into localized hot spots. It has long been predicted that the interior temperatures of collapsing bubbles should reach thousands of K during collapse. Experimental measurements of conditions...

    Using the example of periodically driven multi-bubble systems we demonstrate that it may be misleading to conclude from a successful low dimensional delay reconstruction that the underlying dynamical process is indeed governed by a low-dimensional attractor.
