Multiphase Flow in Porous Media

Jump to navigation Jump to search


Many natural and technical processes involve multiphase flow processes in porous media. Despite that fact fundamental concepts of twophase flow on macroscopic scales still remain unclear. The predictive power of the most commonly used extended multiphase Darcy theory is at best limited to simple problems where neither hysteresis nor dynamic effects like trapping nor varying residual saturations have a substantial impact on the solutions.

Our Project

It is known that percolating and nonpercolating fluid parts show fundamental different behavior (e.g. Abrams (1975), Avraam et al. (1995), Taber (1969), Wyckoff (1936)) and a macroscopic model which takes into account the difference of nonpercolating and percolating fluid parts was proposed by R. Hilfer (1998) and elaborated in succeeding works (see below).
