Physical conditions of the ball lightning ejection caused by interaction of electrical discharge with metal and polymer

Commutation of lightning impulse by multiarc erosive radial-slotted discharge

The non-stationary mode of radial-slotted erosive discharge was considered. The existence condition of the relatively steady multiarc regime has been found. Experimentally it has been shown that this discharge has been corresponding to the required condition at the sufficiently large current. The oscillograms of commutation of lightning impulse on the simulative test facility with the equivalent of a high-voltage transmission line are presented. The obtained results indicate the ability of erosive discharge, when using within the framework of the complex lightning protection facility, to fast …

The Dust-Gas Fireball as a Special Form of the Electric Erosive Discharge Afterglow

Main results of researches of the electric erosive discharge afterglow plasma, of the fireballs being formed by this plasma and having some particular but deep similarities to the ball lightning are given. The analysis of our results and results of some other authors has allowed to specify the nature of radiation and stability of the shape for a dust-gas chemical fireball, to make series of assumptions concerning the mechanism of these properties. The experimental results and considerations of the given work can be interesting for physics of plasma with different kinds of condensed state, for …

Investigation of Vortex Structures in Gas-Discharge Nonneutral Electron Plasma: IV. Pulse Ejection of Electrons at the mutual interaction of Vortex Structures

The results of experimental investigations of the ejection of electrons from gas-discharge nonneutral electron plasma at interaction of vortex structures have been given. The periodical approach of vortex structures causes the ejection of electrons both from the vortex structures themselves and from the adjacent regions of electron sheath to the end cathodes of discharge device. The ejection takes place in the form of short and long pulses following each other. The nature of these pulses and the dynamics of interaction of vortex structures at their approach were studied.

Investigation of Vortex Structures in Gas-Discharge Nonneutral Electron Plasma: III. Pulse Ejection of Electrons at the Formation and Radial Oscillations of Vortex Structure

The results of experimental investigations of electron ejection from gas-discharge nonneutral electron plasma at the formation and radial oscillations of vortex structure have been presented. The electrons are injected from the vortex structure and the adjacent region of electron sheath in the form of pulses the duration and periodicity of which are determined by the processes of evolution and dynamics of this structure. The possible mechanisms of pulse ejection of electrons are considered. The influence of electron ejection on other processes in discharge electron sheath is analyzed.

The Plasma Structures and Networks of Channels as Components of The Sequential Mechanism of Lightning Initiation Within Thunder Clouds

The dissertation describes in detail the experimental studies of the initiation of unusual plasma formations (UPFs) in the electric field of an artificially charged aerosol cloud. These experiments, together with the latest data from the study of intracloud discharges, make it possible to construct a sequential mechanism for initiating lightning inside a thundercloud, as well as a model of compact intracloud discharges (CID/NBE).
