Um estudo da física de sistemas multiplicadores subcríticos acionados por aceleradores
(Universidade Federal de Santa MariaCentro de Ciências Naturais e Exatas, 2008-01-30)
In this work were reviewed the operation principles of subcritical multiplying systems powered by accelerators (ADS) from the point of view of the neutron transport. To do this it was necessary to characterize theoretically ...
Light transport with the equation of radiative transfer: The Fourier Continuation – Discrete Ordinates (FC–DOM) Method
(Pergamon-Elsevier Science Ltd, 2019-10)
We present a method for the treatment of the time dependent radiative transfer equation under the discrete ordinate approximation. The novelty of the proposed approach stems, in part, from the incorporation of a spectral ...
Solução de problemas em semiespaço na dinâmica de gases rarefeitos baseada em modelos cinéticos
(Universidade Federal de Santa MariaBRMatemáticaUFSMPrograma de Pós-Graduação em Matemática, 2012-02-28)
The method discrete ordinates is used to solve problems involving rarefied gas dynamics. In this
work, a version of the analytical method discrete ordinates (ADO) is used to solve problems in a
semi-infinite. The complete ...
Formulacão unificada para modelos cineticos derivados da equação de Boltzmann com condições de contorno generalizadas
(Universidade Federal de Santa MariaBRMatemáticaUFSMPrograma de Pós-Graduação em Matemática, 2012-02-28)
In this paper, we present numerical results obtained from the FORTRAN language for physical quantities of interest such as velocity profile, pro�le, heat ow rate, particle ow rate,heat ux and pressure tensor component. The ...

Estudo da dinâmica de um gás confinado em placas paralelas heterogêneas utilizando o modelo S
(Universidade Federal de Santa MariaBRMatemáticaUFSMPrograma de Pós-Graduação em Matemática, 2011-05-18)
In this work, an analytical version of the method of discrete ordinates (ADO) is used
in developing solutions to problems of rarefied gases confined by two infinite parallel
plates with different chemical constitutions, ...
O modelo de McCormack no escoamento de gases rarefeitos
(Universidade Federal de Santa MariaBRMatemáticaUFSMPrograma de Pós-Graduação em Matemática, 2011-02-24)
In this paper, we present numerical results for macroscopic quantities of interest (velocity
profile, the heat ow profile and shear stress) for the
ow of a binary mixture of rarefied gases in microchannels of arbitrary ...
