Combined mode heat transfer analysis utilizing radiation scaling
Abstract
Scaling laws have been formulated by Lee and Buckins (1982 and 1983) to predict the radiant heat flux in anisotropically scattering one-dimensional planar media. The radiation portion of the problem is reduced to an equivalent nonscattering problem by the scaling. The same scaling laws are applied to problems when radiation is combined with other modes of heat transfer, requiring the solution of the energy equation for a temperature profile. The average incident intensity is accurately scaled by a multilayer approach. Results presented for radiation/conduction and the thermally-developing-Poiseuille-flow problems show very good agreement between exact and scaled solutions for heat fluxes and temperature distributions.
