Abstract

We experimentally demonstrate that chemical reactions, by producing changes in viscosity at the miscible interface between two fluids, can be the very source of viscous fingering in systems that are otherwise stable in the absence of a reaction. We explain how, depending on whether the reaction product is more or less viscous than the reactants, different patterns develop in the reaction zone.
