AbstractAdvanced course in radiation heat transfer
ObjectiveFundamentals of radiative heat transfer for high-temperature applications. Examples are combustion and solar thermal/thermochemical processes, and other applications in the field of energy conversion and material processing.
Content1. Introduction to thermal radiation. Definitions. Basic laws. Properties. Electromagnetic spectrum. Blackbody and
non-black surfaces. Absorptivity, emissivity, reflectivity. Planck's Law, Wien's Displacement Law, Kirchhoff's Law.

2. Surface radiation exchange. Diffuse and specular surfaces. Gray and non-gray surfaces. Configuration Factors. Radiation Exchange. Enclosure Theory. Monte Carlo.

3.Absorbing, Emitting and Scattering Media. Extinction, Absorption, and Scattering Coefficient. Optical thickness.
Equation of radiative transfer. Solution methods: discrete ordinate; zone; Monte-Carlo.

4. Applications. Cavities. Selective surfaces and media. Combined radiation/conduction/convection heat transfer.
