On the stability of electric arc discharges
Journal of Applied Physics, 1976 The stability of electric arc discharges has been explored through the use of an energy balance coupled with charge conservation. In order to facilitate this analysis, a new model for the electrical conductivity function has been proposed. Asymptotic solutions for the arc governing equations have been obtained.

The Electric Arc Discharge in Water
Transactions of The Electrochemical Society, 1933 The solid, soluble and gaseous products of the low‐tension arc discharge in water were investigated. Solid compounds of hydroxide nature were obtained with carbon and metal electrodes. The quantitative effect of water temperature and pressure on the rate of production of gases (reaction rate) was studied; measurements of the arc temperature, and its ...
