Arc Constriction and Anode Heat Transfer in High Intensity Arcs.
Abstract
A new method has been developed for measuring anode heat fluxes in pulsed kiloampere arcs. The method is based on an optical measurement of the temperature history of the rear face of a very thin anode. Matching of experimental with calculated temperature histories for various front surface heat fluxes provides actual quasisteady anode heat fluxes. Results are presented for tungsten and copper anodes in combination with argon and nitrogen as working gases. Anode heat fluxes are primarily influenced by the cathode condition and the working gas. The second part of this report deals with the anode region of a high intensity arc.
