- On the spectral Green’s function-constant nodal method for fixed-source SN problems in , -geometry with arbitrary L’th-order anisotropic scattering Welton Menezes Gustavo Alvarez Ricardo Barros Biología fixed source Energy multigroup discrete ordinates anisotropic scattering Presented here is an extension of the spectral Green’s function-constant nodal (SGF-CN) method for the numerical solution of energy multigroup, fixed-source, discrete ordinates (SN) problems in X, Ygeometry with arbitrary L’th-order of scattering anisotropy, provided L<N. This analytical coarsemesh method uses the multigroup SGF method for numerically solving the one-dimensional transverse-integrated SN nodal equations with constant approximations for the transverse leakage terms. The only approximations in the present version of the SGF-CN method occur in these transverse leakage terms, as the energy-group transfer scattering source terms are treated analytically within the offered method. Numerical results to typical model problems are given to illustrate the method’s accuracy and to analyze the efficiency of the offered SGF-CN computer code for neutral particle transport calculations. 2020 artículo científico 2319-0612 https://www.redalyc.org/articulo.oa?id=722280924027 en http://www.redalyc.org/revista.oa?id=7222 Brazilian Journal of Radiation Sciences application/pdf Sociedade Brasileira de Proteção Radiológica - SBPR Brazilian Journal of Radiation Sciences (Brasil) Num.3A Vol.8
