A method of calculating the temperature profile of high-pressure sodium electric arcs using the diffusion approximation for the radiation flux density is described. Account is taken of energy transfer due to thermal conduction, emission and absorption of radiation. The method has been applied to calculate the temperature profile for a sodium vapor pressure of 250 Torr and the calculated temperature distribution is compared with the result of experimental measurement.
