The transformation of PL solutions for extremely anisotropic scattering to solutions with isotropic scattering and application to the critical slab problem

Journal of Quantitative Spectroscopy and Radiative Transfer, 1993
Abstract The PL solutions for extremely anisotropic scattering are expressed in terms of solutions for isotropic scattering. To see the use of the transformed solutions, applications for variations of the critical thickness with backward scattering are given.

The singular eigenfunction method: The critical slab problem for linearly anisotropic scattering

2020
The critical slab problem for linearly anisotropic scattering is investigated using the singular eigenfunction method. The third form of the transport equation is considered. The singular eigenfunctions for linearly anisotropic scattering are inserted into the Green's function.

Chebyshev polynomial (T_N ) approximation to neutron transport theory and application to the critical slab problem

Kerntechnik, 2008
Abstract The critical slab problem has been studied in the one-speed neutron transport equation with isotropic scattering by using the first kind of Chebyshev Polynomials. The moment criticality solutions were obtained for the uniform finite slab using Mark and Marshak type vacuum boundary conditions.

On the Problem of Heat Transfer in a Phase-Change Slab Initially Not at the Critical Temperature

Journal of Heat Transfer, 1987
A one-dimensional heat transfer problem in the phase-change slab, one side of which is isothermal while the other is insulated, is considered. Both cases—fusion and solidification—are treated. Slab temperature at the intitial moment is assumed constant and not critical.

Unified treatment of the P ^(λ) _n approximation to solve the reflected slab criticality problem with strong anisotropy

Kerntechnik, 2008
Abstract Ultraspherical polynomial P (λ) n approximations are used in reflected slab criticality calculations for strongly anisotropic scattering. A unique formulation is developed for reflected slab criticality conditions whose special cases are spherical ...

Application of the T_N method to critical slab problem for one-speed neutrons with forward and backward scattering and efficiency of reflection coefficient

Kerntechnik, 2010
Abstract The one-speed neutron transport equation which includes isotropic forward and backward scattering has been studied using the TN approximation. Critical thicknesses for different values of the reflection coefficient R and c values have been calculated.

The reflected slab and sphere criticality problem with anisotropic scattering in one-speed neutron transport theory

Progress in Nuclear Energy, 1997
Abstract The one-speed transport equation is applied to a homogenous, one-dimensional multiplying medium with linearly anisotropic scattering. Case's singular eigenfunction method is used to formulate the criticality conditions. In addition to available bi- ortogonality relations in the literature, some parallel relations are derived to obtain the ...

Modified U_N method for the reflected critical slab problem with forward and backward scattering

Kerntechnik, 2011
Abstract The critical slab problem is investigated in one-speed neutron transport theory for reflecting boundary conditions using second kind Chebyshev polynomials approximation. The forward-backward-isotropic scattering kernel is used in a uniform homogeneous slab.

Study of the effect of anisotropic scattering on the critical slab problem in neutron transport theory using Chebyshev polynomials

Kerntechnik, 2008
Abstract The effect of anisotropic scattering on the variation of the critical thickness for one-speed neutrons in a uniform finite slab has been studied using Marshak boundary conditions. Chebyshev polynomials of the second kind are used in the angular part of the neutron flux.
