Abstract:

A simple theoretical model for the high energy pulsed arc discharge has been proposed, in which thermal conduction and radiative transfer occur within the arc. Radiative transfer is discussed both in general and as applied to the model. The theoretical evaluation of the various physical properties of the arc plasma, that are required in finding a solution to the model, including absorptivity, thermal and electrical conductivities are described using simple and relatively complete expressions. Calculations which consider the arc to be of homogeneous temperature of the form of a plane parallel slab and a cylinder are described, with results indicated for the plane parellel slab using a simplified representation of the electron density and absorptivity. Experimental measurements necessary to validate the model are discussed. Measurements of the spectral radiance in the ultraviolet at different radial points are presented. Author
