| Abstract: | A method for solving the saturation equation for two-phase now is presented. The method may
be viewed as an operator splitting method or as an Eulerian-Lagrangian backtracking procedure or as a modi£ed
method of characteristics. For each time step, the method consists of an advection step and a diffusion step. The
advection step requires the tracking of streamlines locally around certain integration points. On each streamline
we have to solve a nonlinear hyperbolic equation. This is done using a front tracking method. The solution
from the tracking step is projected back onto a fixed grid, and we finally have to solve a parabolic heat-type
equation. |
