Lagrangian mixing of pulsatile flows in constricted tubes
Nicasio Barrere, Javier Brum, Maximiliano Anzibar +3
In this work several lagrangian methods were used to analyze the mixing processes in an experimental model of a constricted artery under a pulsatile flow. Upstream Reynolds number…
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…
Characterizing multistability regions in the parameter space of the Mackey-Glass delayed system
Juan P. Tarigo, Cecilia Stari, Cecilia Cabeza +1
Proposed to study the dynamics of physiological systems in which the evolution depends on the state in a previous time, the Mackey-Glass model exhibits a rich variety of behaviors…
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…
Using mobile-device sensors to teach students error analysis
Martin Monteiro, Cecilia Stari, Cecilia Cabeza +1
Science students must deal with the errors inherent to all physical measurements and be conscious of the need to expressvthem as a best estimate and a range of uncertainty. Errors…
