Two phase flow in porous media — •Toby Joseph1 and Rudolf Hilfer1,2 — 1ICA-1, Universität Stuttgart, 70569 Stuttgart, Germany — 2Institut für Physik, Universität Mainz, 55099 Mainz,Germany
Our understanding of two phase flow in porous media is still very incomplete. Although Darcy’s law has been modified to deal with two fluids flowing in a porous medium by introducing extra parameters like the relative permeabilities, its domain of validity is still a matter of scientific debate. Moreover, it is well known that the relative permeability curves are history dependent and even the residual saturations in an invasion process depends on the way in which the invasion is driven as is clear from the capillary saturation curves. We present here a micro-to-macro upscaling that takes into consideration some of these problems.
