Abstract
We report on some surprising structures of particle paths in the velocity field of wavy Taylor vortices using velocity fields from a model of Davey, DiPrima, and Stuart [J. Fluid Mech. 31, 17-52 (1968)]. We observe that there are regions of chaotic mixing in the boundaries between the vortices and, more surprisingly, find evidence of ring vortices propagating azimuthally around the cylinder at the speed of the wave propagation.Keywords
