Influence of coaxial cylinders on vortex breakdown in a closed flow
Cecilia Cabeza, Gustavo Sarasua, Arturo C. Marti +4
The effect of fixed cylindrical rods located at the centerline axis on vortex breakdown (VB) is studied experimentally and numerically. We find that the VB is enhanced for very sma…

Nonlinear dynamics at the interface of two-layer stratified flows over pronounced obstacles
C. Cabeza, J. Varela, I. Bove +6
The flow of a two--layer stratified fluid over an abrupt topographic obstacle, simulating relevant situations in oceanographic problems, is investigated numerically and experimenta…

A simple mechanism for controlling vortex breakdown in a closed flow
C. Cabeza, Gustavo Sarasua, Arturo C. Marti +1
This work is focused to study the development and control of the laminar vortex breakdown of a flow enclosed in a cylinder. We show that vortex breakdown can be controlled by the i…
