Unformatted text preview: ace diffusion coefficient is a weighted harmonic average of the diffusion coefficient for cells and . It is important to recognize that our result for the interface current is geometry-independent. It is not difficult to show that if we write down the balance equation for cell I in slab, cylindrical, and spherical geometry, they can all be expressed generically as follows: () Where ( ) ( { ) And ( { ) ( ) To get our generic interior-mesh diffusion discretization, we simply substitute from Eq. (6) into Eq. (7): ( ) ( ) () Our previous derivation of t...
