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…

Intermittency of bubble deformation in turbulence
Xu Xu, Yinghe Qi, Shijie Zhong +3
The deformation of finite-sized bubbles in intense turbulence exhibits complex geometries beyond simple spheroids as the bubbles exchange energy with the surrounding eddies across…
