Destabilization of a viscous film flowing down in the form of a vertical cylindrical curtain

Résumé

In this letter, we study experimentally a viscous liquid curtain in an annular geometry. Gap and median radius can be varied in such a way that the base of the initially stationary cylindrical curtain is led to oscillate by decreasing the flow rate. Standing and traveling waves in the plane of the annulus are observed and a non-trivial expression linking pulsation to flow rate per surface unit and viscosity can be defined.
