RADIATIVE TRANSFER AND THE SCATTERING PROBLEM
Journal of Quantitative Spectroscopy and Radiative Transfer, 1968Abstract Modification of the radiative transfer in a medium with absorption and emission by different types of scattering is outlined. The physical processes due to scattering change quite considerably the radiative transfer in such case to an extent that the scattering has to be taken into consideration, when a realistic solution is desired.

This paper presents an exact solution to the equations of radiative transfer for a generalization of the Uniform-Picket-Fence model discussed in a previous work. Here the absorption coefficient is allowed to take N different values over the frequency spectrum. Case's method is used to construct the normal mode solutions to the set of N coupled integral

Radiative heat transfer has a totally different form of transmission from heat conduction and heat transfer. In heat conduction and heat transfer, energy is transported by the diffusion caused by the motion, oscillation and rotation of molecules, atoms, electrons of the medium. On the other hand, in radiative heat transfer, the energy is transported by

Thermodynamics and Radiative Transfer [PDF]
, 2010 In this final chapter of Part III, thermal radiation will be studied from various perspectives that go beyond the uniform systems view taken in Chapter 7. The treatment offered here will not be a complete continuum model; rather, we will take a closer look at some aspects that make radiation unique among the heat transfer modes.

Radiative Transfer Modeling for CoBOP
1997Abstract : The overall goal of this work is to take oceanic radiative transfer theory into a new domain: shallow water with highly variable bottom topography and bottom optical properties, including fluorescent bottom substances.

Radiative transfer and irreversibility
Journal of Quantitative Spectroscopy and Radiative Transfer, 1966Abstract The irreversibility of the interaction of radiation with matter is investigated by considering a stationary isothermal gas that emits the resonance line of atoms with only two discrete energy levels. In order to describe such a situation microscopically, the steady-state balance of the occupation numbers of the atomic levels and the equation

We have focused on the turbulent fluid mechanics, the chemical reactions, and the interactions between these two aspects of combustion and gasification. In this chapter we change emphasis and briefly examine the dominant heat-transfer mechanism in coal-fired combustors and gasifiers; namely, radiative heat transfer.

Fundamentals of Radiative Transfer
1966We shall consider the thermal radiation phenomena from macroscopic point of view. Hence our linear dimension in the flow field is larger compared with the wave length of the radiation rays and our time scale is larger compared with the period of all frequencies contained in the radiation rays. In analogy of the theory of gasdynamics, our present theory

A difference scheme for radiative transfer
Journal of Computational Physics, 1969The numerical description of the state of matter which is in the presence of a radiation field, and which scatters, absorbs, and emits that radiation is far from straightforward. Three general methods have been applied to various problems: invariant imbedding, Monte Carlo, and direct discretization of the relevant integrodifferential equations.
