Anomalous kinetics of reactive Fronts in porous media

Abstract : The dynamics of reactive transport phenomena in porous media derive from the interaction of microscopic mass transfer and reaction processes. The understanding of observed reaction behavior requires the quantification of these microscale processes and their impact on the large scale reaction and transport behavior. Here we study the mixing limited (fast) reaction A + B --> C at the pore-scale, and its effective behavior on the mesoscale, as a paradigmatic case that allow us to provide a connection between local mixing properties and global reaction kinetics.
