Energy dependent radiative transfer equation and energy discretization

Radiative Energy Transfer with Filter

An ideal blackbody resides inside a cavity in a medium of temperature T that is also an ideal blackbody. If the small black body is initially at temperature T could its temperature evolve to an equilibrium temperature T ′ different from T if the inner surface of the cavity is covered with a passive filter? For example, the filter might be an ideal transmitter for light of wavelength λ < λf (or ...

Radiative energy transfer in compressible turbulence

This Letter investigates the compressible energy transfer process. We extend a methodology developed originally for incompressible turbulence and use databases from numerical simulations of a weak compressible turbulence based on Eddy-DampedQuasi-Normal-Markovian (EDQNM) closure. In order to analyze the compressible mode directly, the well known Helmholtz decomposition is used. While the compre...

Radiative energy transfer in disordered photonic crystals.

The difficulty of description of the radiative transfer in disordered photonic crystals arises from the necessity to consider on an equal footing the wave scattering by periodic modulations of the dielectric function and by its random inhomogeneities. We resolve this difficulty by approaching this problem from the standpoint of the general multiple scattering theory in media with an arbitrary r...

Radiative Energy Transfer with Filters and Stokes/Anti-Stokes Coatings

An ideal blackbody resides inside a cavity in a medium (heat bath) of temperature T that is also an ideal blackbody. If the small black body is initially at temperature T , could its temperature evolve to an equilibrium temperature T ′ different from T if the inner surface of the cavity were covered with a passive filter? For example, the filter might be an ideal transmitter for light of some w...
