Calculation of the Temperature in a Conductive Track of an Arc on the Surface of a Magnet-Blast Chute

The space and time temperature distribution is analyzed for a conductive track of a high current arc that was burned in the insulating channel of a magnet-blast chute. The thermal conditions in absence of boiling and ablation were considered by a combination of the methods of continuous and instantaneous energy sources, when the energy consumption for the phase transition is assumed to be uniform. The purpose of such analysis was a study of possibilities for using the additional energy absorbtion capacity of chutes by increasing the permissible temperature of their walls up to the boiling point.
