Öz

U1 and P1 approximations are applied to one-dimensional neutron transport equation and HenyeyGreenstein phase function is used for calculating diffusion length. Numerical results obtained from U1 and P1 approximations are compared with each other for different collision parameters and t parameters.

UN Metodu Kullanarak Henyey-Greenstein Faz Fonksiyonu ile Difüzyon Yaklaşımı

Öz

U1 ve P1 yaklaşımları tek boyutlu nötron transport denklemine uygulandı ve difüzyon uzunluğu hesabı için Henyey-Greenstein faz fonksiyonu kullanıldı. Farklı çarpışma parametreleri ve t parametresi için U1 ve P1 yaklaşımlarından elde edilen nümerik sonuçlar birbiri arasında kıyaslandı.
