Generalized theory for multiphase flow in porous media — Oliver Hönig, •Rouven Steinle, and Rudolf Hilfer — Institut für Computerphysik, Universität Stuttgart, 70569 Stuttgart, Deutschland

We study multiphase flow processes, including imbibition and drainage processes, in porous media on macroscopic scales to resolve the shortcomings of the traditional theory. The equations of the fluid percolation model [1] are transformed into a dynamical system with immobile nonpercolating fluid phases. This dynamical system is investigated analytically and numerically. Various classes of travelling wave solutions have been found [2].
