Modeling of a direct-current arc in a plasmatron with step electrodes

By methods of physical modeling using a linear ridge regression it is established that in direct-current plasmatrons with step electrodes the volt-ampere characteristic of the arc is formed by heat-transfer processes, while gasdynamic factors have a slight effect. Generalized VACs of unilateral- and...

Zusammenfassung:	By methods of physical modeling using a linear ridge regression it is established that in direct-current plasmatrons with step electrodes the volt-ampere characteristic of the arc is formed by heat-transfer processes, while gasdynamic factors have a slight effect. Generalized VACs of unilateral- and bilateral-emission plasmatrons in blowing the arc with air and hydrogen are refined.[PUBLICATION ABSTRACT]
