Time-of-flight model of the effect of gas flow rate on the development of a helical arc
Abstract
The development and shape of an electric arc in argon at 0.1 MPa has been studied as a function of the induction of an applied axial magnetic field and argon flow rate. An expression is derived which relates the critical induction to the gas flow rate. Analysis of the results supports the time-of-flight model which assumes that the effect of gas flow rate consists essentially of changing the time during which the arc remains in the supercritical-induction region due to gas-flow induced arc drift.
