Seeing the invisible: convection cells revealed with thermal imaging
Renzo Guido, Mateo Dutra, Martín Monteiro +1
Fluid instabilities are ubiquitous phenomena of great theoretical and applied importance. In particular, an intriguing example is the thermocapillary or Bénard-Marangoni instabilit…
Semi-collapse of turbulent fountains in stratified media and the mechanisms to control their dynamics
Luis G. Sarasua, Daniel Freire Caporale, Nicaso Barrere +1
Turbulent fountains are widespread natural phenomena with numerous industrial applications. Extensive research has focused on the temporal evolution and maximum height of these fou…
Elucidating coherent structures, transport barriers and entrainment in turbulent fountains in stratified media
Daniel Freire Caporale, Nicasio Barrere, Arturo Carlos Martí +2
We analyse the flow organization of turbulent fountains in stratified media under different conditions, using three-dimensional finite-time Lyapunov exponents. The dominant Lagrang…
Development and decay of vortex flows in viscoelastic fluids between concentric cylinders
Renzo Guido, Felipe Rinderknecht, Cecilia Cabeza +2
We study the development and decay of vortex in viscoelastic fluids between coaxial cylinders by means of experiments with solutions of polyacrylamide and glycerin and numerical si…
Spreading height and critical conditions for the collapse of turbulent fountains in stratified media
L. G. Sarasua, D. Freire, C. Cabeza +1
Axisymmetric fountains in stratified environments rise until reaching a maximum height, where the vertical momentum vanishes, and then falls and spread radially as an annular plume…
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…
