Radiative Heat Transfer

This lecture covers advanced topics in heat transfer, focusing on radiative heat transfer in participating media. The instructor discusses the radiative intensity in vacuum, boundary conditions for the radiative transfer equation, radiative heat flux, and the divergence of the radiative heat flux. The lecture also delves into the radiative properties of particle clouds, the radiative characteristics of a single sphere, and the absorption and scattering by spherical particles using Mie theory. Various concepts such as extinction efficiency factor, scattering phase functions, and the geometrical optics limit for large opaque spheres are explored.
