Electrokinetic Flows about Ion-Selective Surfaces
Organizers: Dr. Martin Bazant, Massachusetts Institute of Technology and Dr. Ehud Yariv, Technion - Israel Institute of Technology
Spurred by recent developments in microfluidics and nanotechnology, there is a great current interest in electrokinetic flows about ion-selective structures; examples include electrodes, porous surfaces, ion-exchange beads, and nano-channel arrays. Such flows are fundamentally different from those about inert surfaces, and are characterized by such features as concentration polarization and extended space-charge layers. Emerging applications of such flows include packed-bed chromatography, water purification and desalination, and nanofluidic focusing.
Cardiac Fluid Dynamics: Translating Fundamental Insights into Clinical Practice
Organizers: Dr. R. Mittal, Johns Hopkins University and Dr. P. Vlachos, Virginia Tech.
Cardiac flows, namely flows toward, through and from the heart, are governed by coupled hydrodynamic processes including but not limited to: pulsatility, transition, moving boundaries with large deformations, fluid-structure interactions, separation, vortex formation and hemoacoustics. The objective of this minisymposium is to focus on fluid dynamics research that bridges fundamental insights and clinical practices. We bring together a group of fluid-dynamicists and practicing cardiologists to share their research as well as their views on how fluid dynamics research is having (and can have) an impact on clinical cardiology.
The Fluid Dynamics of Geological CO2 Sequestration
Organizers: Dr. Jerome Neufeld, Cambridge University, Dr. Ruben Juanes, Massachusetts Institute of Technology and Dr. Anja Slim, Schlumberger
The geological sequestration of carbon dioxide is one technological route to significant reductions in CO2 emissions. The fluid dynamics of multiphase porous flow plays a key role in the propagation, possible leakage, and permanent immobilization of CO2 due to its relative buoyancy, the action of capillary forces, through the dissolution of CO2 into ambient brine, and by mineral reactions with the host rock. The study of these mechanisms has laid bare new dynamics in the multiphase flow of fluids in porous media, the nature of high-Rayleigh number porous convection, and the mediation of chemical reactions by porous fluid flows.
