Two distinguished lectures about water and flows
The D-MAVT Distinguished Lecture Series brings world leading scientists and engineers to ETH Zurich. This March, Wolfgang Schröder (Aachen) and David Quéré (Paris), will talk about freely moving particles in viscous flows and Sculpting water.
The D-MAVT Distinguished Lecture Series brings world leading scientists and engineers to ETH Zurich to present their work in a colloquium and to meet with its faculty and students. The colloquium has broad attendance by faculty, staff, Master and Doctoral students from all departments of ETH Zurich.
On 7 March 2016, Wolfgang Schröder, Professor at the RWTH Aachen University will present a Cartesian cut-cell method for viscous flows interacting with freely moving boundaries. The method provides a sharp resolution of the embedded boundaries and strictly conserves mass, momentum, and energy.
The efficiency and the accuracy of the new method are demonstrated for several three-dimensional cases of laminar and turbulent particulate flow such as a spherical particle settling in a quiescent fluid, rotation of an ellipsoidal particle in simple shear flow, and a cloud of particles in homogeneous turbulence.
Sculpting water
21 March 2016, David Quéré Professor at the ESPCI ParisTech and at the École polytechnique Paris will talk about water. Water, and more generally liquids, are shapeless. However, the conjunction of surface tension with external actions such as shocks, centrifugations, etc. allows us to sculpt water, and thus to achieve specific functions.
On David Quéré will discuss in particular how water-repellent materials can be used for such purposes, and which functions can be generated from these «sculptures». He will illustrate this discussion by showing various spectacular applications found in the natural world.
