文摘
- •
A new formulation of the A∞ method for heterogeneous media is proposed.
- •
The kernel of transport equation is approximated as a sum of pure exponential terms.
- •
The transport problem is reduced to coupled equations for homogeneous media.
- •
Four approximations are proposed and the relative equations are presented in detail.
