Philippe Coussot in JNNFM Seminar Series

InterPore member Philippe Coussot will be giving a seminar within the framework of the JNNFM seminar series entitled Progress in rheology and hydrodynamics allowed by NMR or MRI techniques of which half will focus on original applications in porous media.

Abstract
In modern fluid mechanics it has become common to attempt to observe internal flow characteristics even in non-transparent materials. Nuclear magnetic resonance (NMR) offers a wide range of possibilities of non-destructive measurements inside such materials. Indeed, by exciting differently different areas (which leads to magnetic resonance imaging (MRI)), NMR allows to get various information on the physical characteristics of the system at a local scale, such as the liquid content and the displacement or velocity of the liquid molecules, through local or statistical measurements. This presentation will start by a brief overview of the basic technical elements allowing to understand the principles of the technique, its versatility to measure various flow and material characteristics, and the technical difficulties (and costs) inherent to this technique. We will then review applications of NMR in complex flows, rheology of complex fluids, flow in porous media, colloid transport, and fluid transfers in complex porous systems.
