Abstract:

Net radiant heat flow between two infinite, parallel, tungsten plates was computed by summing the monochromatic energy exchange the results are graphically presented as a function of the temperatures of the two surfaces. In general these fluxes range from approximately 8 to 25 percent greater than the results of gray-body computations based on the same emissivity data. The selection of spectral emissivity data and the computational procedure are discussed. Nongray-body computational techniques for determining radiant heat flux appear practical provided the combination of select spectral emissivity data and the proper mechanized data-reduction equipment are brought to bear on the problem.
