Heat Transfer and Attrition Processes at the Anode of Pulsed High Intensity Arcs
Abstract
Tests of a high current pulsed arc with the intent to investigate anode erosion characteristics are described. The range of arc parameters covers currents from 5000 to 10,000 amps (square pulse) with time intervals from (20 to 200) x 10 to the minus 6th power. The arc is designed to be stationary; i.e., there are no external magnetic fields and the arc configuration produces self- magnetic fields which are symmetric so as not to move it. Spectrometric investigations reveal that there is no anode vaporization for the range of parameters investigated. A computer program is described for solving the one- dimensional problem of a constant heat flux impinging on a surface of a material with temperature dependent properties with a liquid-solid interface penetrating the material.
