As in experiments we see branched structures resulting from the Saffman-Taylor instability. We find that the area $A$ of a viscous-fingering cluster varies as a simple power law $A \\sim L^{\\alpha}$ of its interface length $L$. Our results are compared to previously published simulations in which the viscosity of the invading fluid is vanishing. We find differences in exponent $\\alpha$ and in the appearance of detached droplets and bubbles.", "revisions": [ { "version": "v1", "updated": "2014-10-31T07:48:40.000Z" } ], "analyses": { "keywords": [ "viscous fingering", "scaling properties", "simple surface tension law", "central injection geometry", "simple power law" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2014arXiv1410.8659L" } } }
