✦ Synopsis

We describe a system in which vortices are shed from a cylindrical free surface approximately centered in a rotating flow. Shedding is controlled by the parameter e= 2 g/w 2 d, where g, w, d denote gravity, rotation rate and the diameter of the free surface. We find vortex shedding for e>0.162 and no vortex shedding for e < 0.0847. The range depends on the aspect ratio L/d, where L is the column length, in a nonmonotonic fashion. These results are independent of viscosity and surface tension for "small" values of these parameters.
