Sub-surface turbulence and free-surface features
Amélie Ferran, Ali Semati, Anaïs Rouaud +2
Many turbulent flows encountered in nature -- seas, oceans and rivers -- are bounded by a deformable free surface. A question that remained to be fully explored is to what extent t…
Experimental investigation relating free-surface features to sub-surface turbulence
Omer M. Babiker, Jørgen R. Aarnes, Ali Semati +4
Turbulent flows beneath a free surface play a central role in the Earth system, yet their coupling to observable surface features remains incompletely understood. Recent studies us…
Turbulence unsteadiness drives extreme clustering
Florencia Zapata, Sofía Angriman, Amélie Ferran +3
We show that the unsteadiness of turbulence has a drastic effect on turbulence parameters and in particle cluster formation. To this end we use direct numerical simulations of part…
Solar-powered shape-changing origami microfliers
Kyle Johnson, Vicente Arroyos, Amélie Ferran +7
Using wind to disperse microfliers that fall like seeds and leaves can help automate large-scale sensor deployments. Here, we present battery-free microfliers that can change shape…
An experimental study on the settling velocity of inertial particles in different homogeneous isotropic turbulent flows
Amélie Ferran, Nathanaël Machicoane, Alberto Aliseda +1
We propose an experimental study on the gravitational settling velocity of dense, sub-Kolmogorov inertial particles under different background turbulent flows. We report Phase Dopp…
Clustering in laboratory and numerical turbulent swirling flows
Sofía Angriman, Amélie Ferran, Florencia Zapata +3
We study the three-dimensional clustering of velocity stagnation points, of nulls of the vorticity and of the Lagrangian acceleration, and of inertial particles in turbulent flows…
