The Effect of Electrical Conductivity Variations on the Characteristics of Arc Discharges,

摘要

Algebraically calculated current-voltage characteristics of arc discharges are obtained with a canal model for planar and cylindrical arcs and electrical conductivity given as a power of the heat flux potential. For slower than linear variation,the current-voltage characteristic has a distinct minimum whereas for faster than linear variation the arc electric field tends to zero as current increases without limit.
