Abstract:

Sujit Datta

We have recently developed an experimental approach to directly visualize single- and multi-phase flow within a model porous medium, in three-dimensions, both at pore-scale resolution and over continuum length scales. I will describe how we use this approach to quantify and understand (i) pore scale variations in the flow, (ii) how the structure of the medium influences the flow, and (iii) how another, immiscible fluid becomes trapped within, and may be mobilized from, the pore space.
