Wed February 27th 2013 16:00 ZH286 | Seminar | Traffic flows in confined geometries Denis Bartolo |
Details:I will discuss the traffic dynamics of particles advected through model microfluidic geometries. A combination of recent experimental, and theoretical results will be introduced. Long-range hydrodynamics interactions build up between particles cruising in ordered obstacle networks, and in simple Hele-Shaw geometries. These interactions will be shown to be responsible for a wealth of collective traffic phenomena including the propagation of dispersive density waves, and the spontaneous formation of jams akin to the one observed in actual traffic flows. |
