Simple Analytical Model of the Anodic Streamer

Abstract

Key words Preionized electrical discharge, analytical approach, streamer.PACS 51.50.+v, 52.25 Jm In this work, an analytical model is used to study the formation of the anodic streamer in high pressure electrical discharge. This model enabled us to see the space variations of the characteristics of the streamer such as the electric field and the propagation velocity of streamer. The validity of the analytic approach is demonstrated by comparing the model results to the data from the literature. A qualitative concord was found.

Effect of the Electric Discharge Confinement on the Perforation Density of Porous Materials

“…Since Meek and Loeb analyzed the complexity of the spark discharge process in 1940 [2]- [4], many other authors have significantl contributed to increase the understanding of the physical mechanisms involved in this phenomenon. However, the basic description introduced by Meek and Loeb has remained essentially unaltered [5], [6]. The spark discharge process fundamentally consists in the following sequence of events: first the formation of a precursor channel of ionized air between electrodes and, subsequently, the sudden triggering of an electron avalanche travelling from the cathode to the anode in a self-propagating streamer.…”
