Аннотация

An analysis is presented accounting for directional dependence of radiation properties on radiant heat transfer. The system studied is two equal-length plates sharing a common edge. The plates are gray specular reflectors with surface properties characterized by electromagnetic theory for smooth electrical conductors and nonconductors. Numerical results for local and total heat loss are presented for a range of included angles, plate temperature ratios, and hemispherical emissivity values. Local radiant-heat-loss calculations which neglect directional property characteristics can result in significant errors. Total surface heat loss is affected to a lesser degree by directional property variations.
