Chebyshev polynomial (TN) approximation to neutron transport theory and application to the critical slab problem
-
A. Bülbül
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. The results obtained by this approximation are presented in tables which also include the results obtained by the PN method for comparison.
Kurzfassung
Das Kritikalitätsproblem in ebener Geometrie wurde untersucht in der Eingruppen-Neutronentransportgleichung mit isotroper Streuung mit Hilfe von Tschebyscheff-Polynomen erster Ordnung. Die Kritikalitätslösungen für gleichförmige finite Platten wurden mit Hilfe der Vakuum-Randbedingungen vom Typ Mark and Marshak erhalten. Die mit dieser Approximation erhaltenen Ergebnisse werden in Tabellenform vorgestellt. Die Tabellen zeigen zum Vergleich auch Ergebnisse, die mit der PN Methode erhalten wurden.
