UNApproximation for the Eigenvalue Spectrum of Time-Dependent, One-Speed and One-Dimensional Neutron Transport Problem with Anisotropic Scattering
Öz
The eigenvalue
spectrum is studied in one-speed time-dependent neutron transport theory in a
uniform finite slab. The linear anisotropic scattering kernel together with the
combination of forward and backward scattering is used and time-dependent
neutron transport equation is reduced to a stationary one. Numerical results of
eigenvalues for various combinations of the scattering parameters and the
selected values of the time decay constant are performed by using the Chebyshev
polynomials approximation method.

Düzgün
sonlu bir dilimde tek-hızlı zamana bağlı nötron transport teorisinde özdeğer
spektrumu çalışılmıştır. İleri ve geri saçılmayla birlikte lineer anizotropik
saçılma foknsiyonu kullanılmış ve zamana bağlı nötron transport denklemi
kararlı denkleme indirgenmiştir. Nümerik özdeğerler, Chebyshev polinomları
yaklaşımı yöntemi kullanılarak, zaman bozunum sabitinin seçilmiş bazı değerleri
ve saçılma parametrelerinin farklı değerleri için hesaplanmıştır.
