A modification to the random choice method is investigated for solving the equations for multidimensional immiscible displacement in a porous medium. The principal feature of the modification is to represent multidimensional flow correctly by incorporating local properties of the flow into the one-dimensional Riemann solvers of the split random choice method. Advancing fronts are kept accurate and sharp. We perform a numerical experiment using the method to study the stabilizing effect of a small amount of physical capillary pressure on a case for which the advancing front is unstable. 12 references, 14 figures.
