Abstract:

The objective of this experimental and analytical study is to determine the effects of metal vapors on the radiation heat transfer characteristics of arc and plasma systems. A high temperature absorption cell suitable for transmission measurements of alkali metal vapors at temperatures of 300 to 750C with vapor path lengths of 4 to 8 inches is described. The results of calibration tests using the absorption cell and an optical system capable of resolution of 1 to 8 A over the spectral region from 2000 to 9000 A are presented. Typical data on the transmission of sodium vapor are given, and methods of data reduction to obtain spectral absorption coefficients are proposed. A preliminary discussion of the radiation characteristics of vaporized electrode components such as tungsten, copper, and graphite is given. Author
