WebEnter the email address you signed up with and we'll email you a reset link. WebThe first equation is known as the Buckley–Leverett equation (see [1,2,5,12,18,21]). The vector-valued function F [m s 1] and the scalar function [m2 Pa 1 s 1]are respectively referred to as the flux and mobility function. The flux function represents convective transport of the wetting phase and includes gravitational effects.

WebNext, we present a popular approach to reduce the amount of numerical diffusion introduced by upwind approximation ‐ high‐resolution schemes. We compare our implementation of one of the recently proposed central‐upwind schemes against the upwind schemes on several test problems based on Buckley‐Leverett equation and discuss the results. WebThe Buckley--Leverett (nonlinear advection) equation is often used to describe two-phase flow in porous media. We develop a new probabilistic method to quantify parametric uncertainty in the Buckley--Leverett model. Our approach is based on the concept of a fine-grained cumulative density function (CDF) and provides a full statistical description of the …
