Differential Diffusivity Effects in Reactive Convective Dissolution

Fluids, 2018
When a solute A dissolves into a host fluid containing a reactant B, an A + B → C reaction can influence the convection developing because of unstable density gradients in the gravity field. When A increases density and all three chemical species A,
