We study biogeochemical reactions at solid-fluid interfaces under fluid flow conditions combining microfluidics experiments and pore-scale reactive transport modeling. The pore scale investigation will elucidate key mechanisms that govern the interplay between fluid flow and biogeochemical reactions. Experimental findings at pore scale will be incorporated in pore-scale models which will provide the framework for capturing macroscopic phenomena. Three ongoing research topics are:
- Fracture dissolution
- Coupling between biogeochemistry and fluid flow in extreme subsurface environments
- Biofouling and biodegradation in porous media
Figure below shows two different iron precipitation patterns caused by change in hydrodynamic conditions.
More details will be updated soon.
