From macro- to nano-flows

Abstract:
The properties of fluids dynamics in extremely small systems and in the vicinity of interfaces have been discussed from the very beginning of hydrodynamics, but now occupy an increasingly important place in contemporary science and technology. One may cite many examples : miniaturized fluidic systems to develop lab-on-a-chip devices; fluid dynamics in biological systems and the locomotion at small Reynolds number; nanofluidics and flows in nanopores and nanotubes; etc.
In this talk, I'll discuss theoretical and experimental efforts performed over the recent years in our group to characterize and understand the fluid dynamics at solid interfaces, from the macro- to the nano- scales. I will focus in particular on the question of hydrodynamic slippage at nano- and micro- scales, as well as its implications on the nano-hydrodynamics within the Debye layer and interfacial (osmotic) driving [1].
