Micro-PIV Measurements of Multiphase Flow in Deforming Porous Media Subject to Mineral Dissolution
Keywords:Micro-PIV, Porous media, Multiphase flow, Mineral dissolution
Mineral dissolution is studied in novel calcite-based porous micromodels under single- and multiphase conditions, with a focus on the interactions of mineral dissolution with pore flow. Microscopic particle image velocimetry (PIV) was utilized to simultaneously characterize the local velocity field and the instantaneous shapes of the dissolving grains. The preliminary results provide a unique view of the coupled dynamics between pore flow and mineral dissolution.
