Abstract (AI)
Thermal energy transport by radiation is unique compared to conduction and convection in that a transport medium is not required. In fact, heat transfer by radiation between two surfaces is greater when there is no intervening material. Fortunately the absorption of radiation between surfaces within many electronic enclosures is such that this absorption is neglected throughout this text.
Key Findings
1
Analyses of radiation exchange are given for: black isothermal surfaces, enclosures of diffuse gray surfaces, enclosures with some specular reflections, and nondiffuse nongray surfaces.
2
Comprehensive treatment of thermal radiation heat transfer covering material radiative behavior, surface-to-surface exchange, and gas radiation mechanisms.
3
Electromagnetic theory is used to predict material radiative properties and compared with observed properties of solids.
4
Formulation and discussion of radiative transfer equations for absorbing-emitting gases and for scattering and absorbing media are provided.
5
Monte Carlo techniques are presented and explained for solving radiant-exchange problems and radiative transfer through absorbing-emitting media.
