Multiphase Dynamics and Mass Transport at different Scales


Contact:  Prof. Dr. Helmut Geistlinger

The influence of pore structure and wettability (i) on the dynamics of the fluid-fluid pattern, (ii) on the geometry of gas-water interface and (iii) on the mass transfer kinetics (evaporation) is investigated at pore scale using X-ray microtomography (µ-CT) and micromodel experiments (high-resolution optics, fluorescence spectroscopy). This provides the experimental basis, to achieve a better understanding and description of multi-phase dynamics depending on pore structure and surface properties at a larger scale. Percolation theory and Universal Scaling laws are used to understand “slow” dynamics and mass transfer kinetics at pore scale. These results will help to quantify multi-phase dynamics at continuum scale (REV-scale) with respect to an effective description of material properties (pressure-saturation relationship, conductivities, phase continuity). The expected results will provide a significant contribution to improve modeling of multi-phase flow in porous media. This applies not only to the flow of water- and gas in soils, but also to gas storage processes for (geo-) technical operations (C-sequestration, soil and groundwater remediation) and to technical applications (e.g. multi-phase flow in fuel cells).
