Rotating polygon instability of a swirling free surface flow.
We explain the rotating polygon instability on a swirling fluid surface [G. H. Vatistas, J. Fluid Mech. 217, 241 (1990) and Jansson et al., Phys. Rev. Lett. 96, 174502 (2006)] in terms of resonantExpand

Generation of three-dimensional patterns through wave interaction in a model of free surface swirling flow
The free surface flow in a cylindrical tank over a rotating bottom is known to support spectacular three-dimensional patterns, including deformation of the inner free surface into the shape ofExpand

Waves and instabilities in rotating free surface flows
The stability properties of the rotating free surface flow in a cylindrical container is studied using a global stability approach, considering successively three models. For the case of solid bodyExpand

On the instabilities of a potential vortex with a free surface
In this paper, we address the linear stability analysis of a confined potential vortex with a free surface. This particular flow has been recently used by Tophoj et al. (Phys. Rev. Lett., vol.Expand

Synchronized flutter of two slender flags
The interactions and synchronization of two parallel and slender flags in a uniform axial flow are studied in the present paper by generalizing Lighthill's Elongated Body Theory (EBT) and Lighthill'sExpand

Waves in Newton's bucket
The motion of a liquid in an open cylindrical tank rotating at a constant rate around its vertical axis of symmetry, a configuration called Newton’s bucket, is investigated using a linear stabilityExpand

Flutter and resonances of a flag near a free surface
Abstract We investigate the effects of a nearby free surface on the stability of a flexible plate in axial flow. Confinement by rigid boundaries is known to affect flag flutter thresholds andExpand
