| Zusammenfassung |
| We report the results of experimental and numerical studies of
two-phase flow in a simple analog model of porous medium using a
rectangular network of microfluidic channels. This geometry promotes
the formation of anisotropic, dendrite-like structures during viscous
fingering experiments. The dendrites then compete with each other for
the available flow, which may lead to the appearance of a scale-free,
hierarchical growth pattern. Combining experiments and numerical
simulations, we analyze different growth regimes in such a system,
depending on the network characteristics and fluid miscibility. |
