Experimental Investigation of the Current Density and the Heat‐Flux Density in the Cathode Arc Spot

  • Published:
Journal of Engineering Physics and Thermophysics Aims and scope

Abstract

New experimental data on the effective “thermal” density of a current in the nonstationary arc spot on the copper cathode of an electric‐arc heater of a gas and its dependence on the magnetic field have been obtained by thermophysical methods. Results of the investigation can be used for thermal calculations of electrodes for the purpose of increasing their service life.
