THERMAL RADIATION SHIELDING FOR HIGH TEMPERATURES.

Abstract

A limited analytical study of thermal radiation shielding for high temperature applications was conducted. Two problems were considered: zero thickness-infinite parallel planes in vacuum, and finite thickness-infinite parallel planes in a monatomic gas atmosphere. Limited results are depicted graphically for several cases. In addition, the results include criteria for determining the proper shield spacing to suppress natural convection of the gas between the shields. The major conclusion is that the total normal emissivity of the shields is the controlling parameter. The thermal conductivity of the shield and of the gas is not significant for the range of variables studied. (Author)
