Abstract

Abstract The dissolution patterns resulting from the unstable dissolution of a porous medium (plaster) by a reactive fluid (water) are quantified as fractals. The effect of the flow rate is studied and shown to yield (1) compact structures at low rates (Peclet numbers lower than unity), (2) fractal structures at intermediate rates, and (3) homogeneous dissolution at high rates. The transition between these two last types is discussed considering the finite sample size and the rock heterogeneity. Quantitative computer simulations on networks support the experimental results and their physical interpretation.
