AN EXPERIMENTAL STUDY OF RADIANT ENERGY TRANSFER FROM A PLASMA

Abstract

A thermistor bolometer has been used to determine the radiant energy transfer from a typical laboratory plasma. Radiation has been found to be a significant mechanism of energy transfer from an atmospheric argon plasma jet, amounting to as much as 18 percent of the net power input to the plasma. The radiant energy transfer from an atmospheric nitrogen plasma jet under comparable conditions has been found to be less than 1 percent of the net power input to the plasma. The radiative power density in an atmospheric argon plasma has been determined. Contributions from both bremsstrahlung and recombination radiation have been found to be important. A model, based on the Kramers and the Unsold approximations, has been used to predict the radiative power density in an atmospheric argon plasma.
