RADIANT ENERGY LOSS FROM A CESIUM-ARGON PLASMA TO AN INFINITE PLANE PARALLEL ENCLOSURE,
Abstract
An integral equation dependent on the spectral absorption coefficient is derived for the radiant energy flux to the wall of an infinite plane parallel enclosure. An approximate spectral absorption coefficient for any alkali metal vapor is found for both continuum and line radiation. Specific calculations are performed for a cesium-argon mixture with a cesium atom density of 10 to the 16th power cc, an argon pressure of 1 atmosphere, an argon temperature of 2000K, and electron temperatures of 2000 K, 2500 K, and 3000 K. The flux to the wall is then computed numerically for planes separated by 1 cm, 10 cm and 100 cm. Continuum, line, and total radiation losses are given for each of the nine cases treated. The magnitude of the results indicates that radiant energy losses are not to be neglected in practical calculations based on a two-temperature model. (Author)
