ACS Algorithm in Discrete Ordinates for Pressure Vessel Dosimetry

open access: yesEPJ Web of Conferences, 2016
The Adaptive Collision Source (ACS) method can solve the Linear Boltzmann Equation (LBE) more efficiently by adaptation of the angular quadrature order. This is similar to, and essentially an extension of, the first collision source method.

On the effects of high-order scattering in 3D cubical and rectangular furnaces [PDF]

open access: yes, 2008
The discrete ordinates method (DOM/Sn) is implemented to investigate the high order scattering effects of absorbing–emitting–scattering grey gas media inside the three-dimensional cubical and rectangular furnaces.

Neutron angular flux reconstruction in slab geometry using multigroup discrete ordinates transport models

open access: yesBrazilian Journal of Radiation Sciences, 2023
In this article, we present an application of the coarse-mesh Deterministic Spectral Method (SDM) to generate multigroup angular fluxes in one-dimensional spatial domains using the neutron transport stationary equation, in the formulation of discrete ...

Goal-based h-adaptivity of the 1-D diamond difference discrete ordinate method. [PDF]

open access: yes, 2017
The quantity of interest (QoI) associated with a solution of a partial differential equation (PDE) is not, in general, the solution itself, but a functional of the solution.

To the solution of the equation of transfer of radiation by method of discrete ordinates in the axisymmetric domain

open access: yesИзвестия высших учебных заведений: Проблемы энергетики, 2018
In this work the method of discrete ordinates is applied for the solution of the problem of transfering of radiation in a finite axisymmetric domain. Decisions for the conditions to model an absorbing medium are obtained.
