TRANSIENT TEMPERATURE DISTRIBUTION IN ELECTRODES WITH MOVING ARCS.

Abstract

An analysis is made of the transient heat transfer process resulting from the passage of a moving electric arc over an electrode. The analysis follows Rosenthal's initial efforts on moving heat sources. The general equation was expressed in a finite-difference form and the results were obtained by utilizing a digital computing machine program. A description and listing of the program is included. In addition, an approximate analysis using an electrical analogy was made and a rudimentary dimensional analysis correlation is presented. The results of these latter two analyses are expected to be useful for electrode temperature predictions. The results of the analyses indicate that, for the typical operating conditions considered, use of relatively thin copper electrodes result in minimum electrode surface temperatures. (Author)
