Description
The free surface deformation generated by a disk rotating at the bottom of a container partially filled with fluid
is an exciting challenge for numerical simulations. The shape of the free surface has shown surprising
patterns in experiments performed by different research groups. However, for many regimes (non
axisymmetric, dewetted disk, sloshing), an accurate comparison with numerical simulations is clearly
missing. We will present the different existing regimes of such flow and show results of comparison between
different numerical codes on few selected regimes. Some preliminary measurements on a recent
experimental set up will also be presented and we will discuss the relevance of a benchmark on such flow.
