Ignition of nanosecond discharge in liquids: Cavitation bubble, bushy and filamentary discharge

Research output: Chapter in Book/Report/Conference proceedingConference contributionpeer-review

Abstract

Three scenarios can be observed in polar dielectrics (deionized water and ethanol) under a nanosecond positive HV pulse depending on HV pulse amplitude. Two discharge modes ('bush-like' and 'tree-like') and cavitation mode are characterized by different morphology, propagation velocity and initial pressure. Dynamics of cavitation mode is analysed in terms of Rayleigh model. Initial cavity size in deionized water, ethanol and n-pentane agrees with the predictions of numerical simulations performed by other authors.
