G0601-5-2 Theoretical study on heat flux of magnetically driven arc

Abstract

The variation of heat flux from the arc with magnetic flux density was theoretically considered under the DC magnetic field imposed perpendicularly to the arc. To simplify the theoretical model, two-dimensional heat flow was transformed into one-dimensional heat flow. Experiment was carried out to measure the heat flux distribution using a specially designed calorimeter. The comparison of experimental result with theoretical predictions confirmed the validity of the assumptions used in the theoretical model.
