Spectral spherical harmonics discrete ordinate method

Journal of Quantitative Spectroscopy and Radiative Transfer, 2021
Abstract A new method for modeling the radiative transfer in inhomogeneous three-dimensional media illuminated by a Gaussian beam is described. This approach, called the Spectral Spherical Harmonics Discrete Ordinate Method (SSHDOM), uses the Fourier expansion method to transform the three-dimensional radiative transfer into an one-dimensional ...

Particular Solution of the Discrete-Ordinate Method

Applied Optics, 2004
We present two methods that can be used to derive the particular solution of the discrete-ordinate method (DOM) for an arbitrary source in a plane-parallel atmosphere, which allows us to solve the transfer equation 12-18% faster in the case of a single beam source and is even faster for the atmosphere thermal emission source.

PARALLELIZATION OF THE DISCRETE ORDINATES METHOD

Numerical Heat Transfer, Part B: Fundamentals, 1997
Abstract Two different paraUetization strategies of the discrete ordinates method (DOM) are described and implemented in a distributed-memory computer. In the angular decomposition (ADP), each processor performs the calculations for the whole domain but deals only with a few directions, while in the spatial domain decomposition (DDP), each processor ...

On the Discrete-Ordinates Method via Case's Solution

Journal of Computational Physics, 1993
Regular and singular solutions of the neutron transport in the plane are considered. A new set of quadrature coefficients for the discrete ordinates method is obtained and its efficiency demonstrated.

Acceleration techniques for the discrete ordinate method

Journal of Quantitative Spectroscopy and Radiative Transfer, 2013
In this paper we analyze several acceleration techniques for the discrete ordinate method with matrix exponential and the small-angle modification of the radiative transfer equation. These techniques include the left eigenvectors matrix approach for computing the inverse of the right eigenvectors matrix, the telescoping technique, and the method of ...
