Free-surface curvature and its relation to subsurface turbulence
Daniel J. Ruth, Filippo Coletti
The free surface atop a turbulent liquid flow is deformed by the underlying fluid motion, with the turbulence imprinting its geometry on the surface. Here we develop a theoretical…
Small-scale dynamics and structure of free-surface turbulence
Yinghe Qi, Yaxing Li, Filippo Coletti
The dynamics of small-scale structures in free-surface turbulence is crucial to large-scale phenomena in natural and industrial environments. Here we conduct experiments on the qua…
Restricted Euler dynamics in free-surface turbulence
Yinghe Qi, Zhenwei Xu, Filippo Coletti
The small-scale velocity gradient is connected to fundamental properties of turbulence at the large scales. By neglecting the viscous and nonlocal pressure Hessian terms, we derive…
Structure and energy transfer in homogeneous turbulence below a free surface
Daniel J. Ruth, Filippo Coletti
We investigate the turbulence below a quasi-flat free surface, focusing on the energy transport in space and across scales. We leverage a large zero-mean-flow tank where homogeneou…
