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…
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…
