A study of the radiative transfer equation using a spherical harmonics-nodal collocation method

Capilla Romá, Maria Teresa; Talavera Usano, César Félix; Ginestar Peiro, Damián; Verdú Martín, Gumersindo Jesús (Elsevier, 2017)

[EN] Optical tomography has found many medical applications that need to know how the photons interact with the different tissues. The majority of the photon transport simulations are done using the diffusion approximation, ...
Analysis of the PHWR benchmark transient using a high-order spherical harmonics-nodal collocation method and treatment of rod cusping effect

Capilla Romá, Maria Teresa; Talavera Usano, César Félix; Ginestar Peiro, Damián; Verdú Martín, Gumersindo Jesús (Elsevier, 2021-05)

[EN] We develop and validate node homogenization methods, based on one and three-dimensional node equivalent problems, that improve the volume weighted method for the treatment of the rod cusping effect. The numerical ...
Application of a nodal collocation approximation for the multidimensional P-L equations to the 3D Takeda benchmark problems

Capilla Romá, Maria Teresa; Talavera Usano, César Félix; Ginestar Peiro, Damián; Verdú Martín, Gumersindo Jesús (Elsevier Masson, 2012-02)

PL equations are classical approximations to the neutron transport equations, which are obtained expanding the angular neutron flux in terms of spherical harmonics. These approximations are useful to study the behavior of ...
