Space-angle discontinuous Galerkin method for plane-parallel radiative transfer equation

Journal of Quantitative Spectroscopy and Radiative Transfer, 2019
The radiative transfer equation (RTE) for a plane-parallel problem involving scattering, absorption and radiation is solved using the discontinuous Galerkin (DG) finite element method (FEM).

The rosseland approximation for the radiative transfer equations

Communications on Pure and Applied Mathematics, 1987
The radiative transfer system of equations for unknown functions \(u^{\epsilon}=u^{\epsilon}(x,\Omega,\nu)\), \(T^{\epsilon}=T^{\epsilon}(x)\) \((x\in X\subset R^{N+1}\), \(\Omega\) is unit direction vector, \(\nu >0)\) is considered. Results of Rosseland approximation are given and the existence of a solution of the radiative transfer system is proved.

Vectorial finite elements for solving the radiative transfer equation

Journal of Quantitative Spectroscopy and Radiative Transfer, 2018
The discrete ordinate method coupled with the finite element method is often used for the spatio-angular discretization of the radiative transfer equation. In this paper we attempt to improve upon such a discretization technique.

Validity conditions for the radiative transfer equation

Journal of the Optical Society of America A, 2003
We compare the radiative transfer equation for media with constant refractive index with the radiative transfer equation for media with spatially varying refractive indices [J. Opt. A Pure App. Opt. 1, L1 (1999)] and obtain approximate conditions under which the former equation is accurate for modeling light propagation in scattering media with ...

Small-angle modification of the radiative transfer equation for a pseudo-spherical atmosphere

, 2013
The conventional pseudo-spherical technique relies on the separation of the total radiance into the direct solar beam and the diffuse radiance; the direct solar radiance is treated in a spherical geometry, while the diffuse radiance is computed in a ...

On the Use of a Direct Radiative Transfer Equation Solver for Path Loss Calculation in Underwater Optical Wireless Channels

IEEE Wireless Communications Letters, 2015
In this letter, we propose a fast numerical solution for the steady state radiative transfer equation in order to calculate the optical path loss of light propagation suffering from attenuation due to the absorption and scattering in various water types.
