    "abstract": "We investigate the stabilization mechanisms of the invasion front in\ntwo-dimensional drainage displacement in porous media by using a network\nsimulator. We focus on the process when the front stabilizes due to the viscous\nforces in the liquids. We find that the capillary pressure difference between\ntwo different points along the front varies almost linearly as function of\nheight separation in the direction of the displacement. The numerical results\nsupport arguments that differ from those suggested earlier for viscous\nstabilization. Our arguments are based upon the observation that nonwetting\nfluid flows in loopless strands (paths) and we conclude that earlier suggested\ntheories are not suitable to drainage when nonwetting strands dominate the\ndisplacement process. We also show that the arguments might influence the\nscaling behavior between the front width and the injection rate and compare\nsome of our results to experimental work.",
