Viscous Fingering on Percolation Clusters
The physical phenomena that occur when a low-viscosity fluid is forced into a high-viscosity one, inside a porous medium (e.g. water pushing oil in a rock), are clearly of much practical interest. These phenomena became the center of much recent scientific interest when it was realized that under some conditions flow instabilities yield viscous fingers (VF) [1,2,3], that are fractal [4,5,6. Fractals are self-similar objects, which look the same at different magnifications .
