| Zusammenfassung |
| Flow and transport in porous media is of great interest in Earth Science, including oil
extraction and groundwater hydrology. The disordered pore-structure leads heterogeneous
flow patterns and preferential flow paths. Here we show how the fluid’s rheology can be used
to control the transport properies inside a porous medium. We find that for a Bingham type
rheology, the fluid has a characteristic Reynolds number for which the flow is least localized,
resulting in enhanced channelized transport. The increased channelization of the flow leads to
a corresponding maximum in permeability. This result has important consequences for the
design of chemical reactors, heat transfer and reactive transport in porous media in
general. |
