Abstract
Two-phase flow systems in porous media have complex dynamics. It is well established that a wide range of system parameters like viscosities and porosity as well as flow parameters such as pressure gradient and fluid saturation have strong impact on the dynamics. The transition from single-phase flow to two-phase flow is a dynamical phase transition. We discuss the order of the transition and investigate the phase diagram in parameter space, using a network simulator for two-phase flow. A semi-empirical theory for the location of the phase boundaries is provided.
