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

Abstract

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 an ascertainment of the chemiluminescence mechanism of the flame, as well as for a bead lightning understanding and for improvement of ball lightning laboratory analogues.
