Vortex dynamics and transport phenomena in stenotic aortic models using Echo-PIV
Javier Brum, Miguel Bernal, Nicasio Barrere +2
In this work, we propose a novel approach which combines ultrasound with Eulerian and Lagrangian descriptors, to analyse blood flow dynamics and fluid transport in stenotic aortic…

Vortex dynamics under pulsatile flow in axisymmetric constricted tubes
Nicasio Barrere, Javier Brum, Alexandre L'Her +2
An improved understanding of how vortices develop and propagate under pulsatile flow can shed important light on the mixing and transport processes including the transition to turb…

Drastic slowdown of shear waves in unjammed granular suspensions
J. Brum, J. -L. Gennisson, M. Fink +2
We present an experimental investigation of shear elastic wave propagation along the surface of a dense granular suspension. Using an ultrafast ultrasound scanner, we monitor the s…
