Electrohydrodynamic self-synchronization of self-oscillations on two diaphragm current concentrators in electrolyte

This work presents the result of experimental studying the mechanisms of self-synchronization of electrohydrodynamic self-oscillation processes in electrolyte for two current concentrators of different size performed in the form of holes in dielectric diaphragms.When an inductance coil is connected to a discharge circuit, a phase synchronization of self-oscillations occurs and is realized as a result of energy accumulation in the coil at the stage of current rise and energy release during the overlapping the current channel by a bubble. The difference in self-synchronization mechanisms is due to small and great spread in concentrator sizes. When having small spread in concentrator sizes, the energy released before the overlapping the concentrators by bubbles is sufficient to provide a synchronization, and when having great spread in concentrator sizes, the energy is required to be released after the overlapping the concentrators due to gas ionization in bubbles.
