3 examples of radiation heat transfer

Energy transfer in the form of electromagnetic radiation

Radiative transfer (also called radiation transport) is the physical phenomenon of energy transfer in the form of electromagnetic radiation.

Convection heat transfer

The propagation of radiation through a medium is affected by absorption, emission, and scattering processes. The equation of radiative transfer describes these interactions mathematically. Equations of radiative transfer have application in a wide variety of subjects including optics, astrophysics, atmospheric science, and remote sensing.

Analytic solutions to the radiative transfer equation (RTE) exist for simple cases but for more realistic media, with complex multiple scattering effects, numerical methods are required. The present article is largely focused on the condition of radiative equilibrium.^[1][2]

Definitions

The fundamental quantity that describes a field of radiation is called spectral radiance in radiometric terms (in other fields it is often called specific intensity).
