Correlation between results of zone method and experiment in radiative heat transfer
Abstract
The zone method is used to simulate the radiative and conductive heat transfer characteristics of an engineering test facility. The results obtained with the zone method are compared to those measured in the subject facility, and it is found that the theoretical and experimental results agree within five percent when the effective wall emissivity is taken to be 0.25. This effective wall emissivity is the product of the actual wall emissivity times the self-absorption factor of the radiation in the cool boundary layer.
