| Abstract: | In this paper a finite volume method for solving particle transport equations is studied, in which the discrete ordinate technique is applied to angular variable and the subcell balance (SCB) scheme is applied to spatial variable. The stability and convergence of the numerical solution are proved by using energy estimation method. Numerical examples are included to demonstrate the performance of the method. |
| Keywords: | particle transport equation subcell balance scheme stability convergence |
