Analytical and Numerical Solution for One-Dimensional Two-Phase Flow in Homogeneous Porous Medium
Original language description
The article presents a comparison of a semianalytical and a numerical approach to a one-dimensional flow-function model of two-phase flow through a homogeneous porous medium which is used for validation of more complex numerical models of two-phase flow.This approach is used in its improved version so that we are able to readily obtain the wetting-phase saturation for all parameter values. To enlarge the class of admissible boundary and initial conditions, we propose another approach which relies on anumerical algorithm which solves the flow-function model equation, based on the finite-difference method in space and time, yielding values of the solution at given time moments and on a spatial grid of positions. Our approach is demonstrated in a seriesof one-dimensional computations showing the accuracy, efficiency, and generality of the proposed algorithms.
