Radiation Exchange Between Surfaces
Chapter 1 Radiation Exchange Between Motivation and ObjectivesThermal Radiation , as you know, constitutes one of the threebasic modes (or mechanisms) of heattransfer, , conduction , convection, and Radiation . Actually, on a physical basis, there are onlytwo mechanisms of heat transfer; diffusion (the transfer of heat via molecular interactions) andradiation (the transfer of heat via photons/electomagnetic waves). Convection, being the bulktransport of a fluid, is not precisely aheattransfer physics of Radiation transport are distinctly differentthan diffusion transport. The latteris alocalphenomena, meaning that the rate of diffusion heat transfer,at a point in space, preciselydepends only on the local nature about the point, , the temperature gradient and thermalconductivity at the point.
