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.
