Abstract
Nonlinear interactions of chemical reactions and viscous fingering are studied in porous media by direct numerical simulations of Darcy’s law coupled to the evolution equation for the concentration of a chemically reacting solute controlling the viscosity of miscible solutions. Chemical kinetics introduce important topological changes in the fingering pattern: new robust pattern formation mechanisms such as droplet formation and enhanced tip splitting are evidenced and analyzed.Keywords
