Don’t miss the NGWREF 2014 Darcy Lecture Series in Groundwater Science farewell presentation from Dorthe Wildenschild, Ph.D. at this year’s Expo.
What Happens in the Pore, No Longer Stays in the Pore: Opportunities and Limitations for Porous Media Characterization and Process Quantification Using X-ray Tomography
Dorthe Wildenschild, Ph.D.
During this presentation, you will receive an overview of the current state of imaging of porous media systems — and processes taking place within them — using x-ray tomography, a technique that allows for three-dimensional observation and measurement of variables internal to an otherwise opaque object. Gain insight on how x-ray tomography has advanced to the point where it is possible to probe porous media in great detail, allowing for fully quantitative analyses of processes and mechanisms at the pore scale. Applications of the technique for the remediation of non-aqueous phase liquid in groundwater, the fundamentals of multiphase flow, and the geologic sequestration of carbon dioxide will be presented.Also discussed will be technique limitations, as well as new potential advances that will allow for exciting new research in coming years.
Dorthe Wildenschild, Ph.D., is an associate professor in the School of Chemical, Biological and Environmental Engineering at Oregon State University.
