Convection and Mixing in a nanometer-thin membrane — •Markus Abel1, Michael Winkler1, Guggi Kofod1, Rumen Krstev2, and Silke Stöckle3 — 1Universität Potsdam, Institut für Physik und Astronomie — 2NMI Naturwissenschaftliches und Medizinisches Institut an der Universität Tübingen — 3Max-Planck-Institut für Kolloid- und Grenzflächenforschung
We investigate experimentally the convection and resulting mixing properties in a very thin membrane positioned vertically. Due to local heating or cooling a convection pattern can be created. The convection can be followed by optical tracking of the film thickness by means of interference finges. We consider the mixing properties of the motion and the related transport of the relevant physicla quantities.
