Abstract:

A systematic procedure is introduced for determining the radiant heat transfer between a radiating gas flame and a gray receiving surface in a closed chamber consisting of n gray surfaces, all of different emissivities. The effect of radiating beam length on the absorptivity of the gas or flame is considered. The resulting equations are then modified for the calculation of radiant heat transfer between gray surfaces in an enclosure separated by nonabsorbing media. The solution and particularly the method presented have wider application than those heretofore published. For numerical calculation, the results can be obtained readily from the digital computer.
