Stabilising effect of the Coriolis forces on a viscous liquid film flowing over a spinning disc

A model developed for the description of finite-amplitude wave regimes in a film flowing over a spinning disc is used to explain the stabilizing role of the Coriolis forces. As in the case of waves on a falling film, a linear relationship between the wave velocity and the maximum of the film thickness has been determined for axisymmetric waves in a film flowing over a spinning disc.
