  • Descrição: The phenomenon of self-synchronization of electrohydrodynamic (EHD) autooscillatory processes during multichannel discharges in electrolyte was observed. The fundamental possibility of the synchronous generation of EHD autooscillations using a system of current concentrators was demonstrated by producing discharges in an aqueous sodium chloride solution using N = 2, 5, 32, and 56 current concentrators with a diameter of 0.2–0.5 mm and a relative size variance up to 0.37. The concentrators had the form of holes or metal electrodes in a dielectric plate. It is established that the mutual synchronization of EHD oscillatory processes in a system involving N current concentrators is ensured by an additional inductance in the discharge circuit. The process of self-induction accompanying current breakage by bubbles leads to the generation of overvoltage in the circuit, which provides synchronous discharge-breakdown initiation on the concentrators and ensures phase synchronization in the system.
