Abstract: Regimes of electrohydrodynamic (EHD) self-oscillations on linear and circular current concentrators (metal stripes, rings, and dielectric circular diaphragms) have been realized and studied for the first time. It is established that the switching of current in these systems is related to the formation of a cylindrical (for linear electrodes) or toroidal bubble (for circular electrodes). The stable development of EHD self-oscillations is ensured by the hydrodynamic coalescence of expanding local bubbles into a common bubble, followed by its geometric leveling due to breakdowns in the gaps between the bubbles and diaphragm.
