From: Channeling is a distinct class of dissolution in complex porous media
Pore structure and acid concentration during mineral dissolution in (A) Model A and (B) Model B at Pe and Ki ranging from 0.01 to 100 at a porosity of 0.57. The solid phase is rendered in grey and the acid concentration in colors. The pore throats extracted using a watershed algorithm are shown in white. Simulations categorised in the compact, wormhole, and uniform regimes are outlined in gray, blue, and green, respectively, while simulations that do not fit into any traditional regime are outlined in red and designated channeling. (C,E) Porosity–permeability curves for all the Model A and Model B simulations, respectively. (D) Porosity–permeability curves for selected (starred) simulations.
