Resolvent model-based analyses of coherent structures in Langmuir turbulence
Anqing Xuan, Lian Shen
We present an analysis of the coherent structures in Langmuir turbulence, a state of the ocean surface boundary layer driven by the interactions between water waves and wind-induce…

Diffusion-based Models for Unpaired Super-resolution in Fluid Dynamics
Wuzhe Xu, Yulong Lu, Lian Shen +2
High-fidelity, high-resolution numerical simulations are crucial for studying complex multiscale phenomena in fluid dynamics, such as turbulent flows and ocean waves. However, dire…

Vortex structures under dimples and scars in turbulent free-surface flows
Jørgen R. Aarnes, Omer Babiker, Anqing Xuan +2
Turbulence beneath a free surface leaves characteristic long-lived signatures on the surface, such as upwelling 'boils', near-circular 'dimples' and elongated 'scars', easily ident…
