Direct numerical simulation of turbulence amplification in a strong shock-wave/turbulent boundary layer interaction

Y Kang, S Lee - Physics of Fluids, 2024 - pubs.aip.org
In this study, the turbulence amplification mechanism within the strong shock-wave/turbulent
boundary layer interaction is investigated using direct numerical simulation (DNS) over a 24 …

Vortex imprints on a free surface as proxy for surface divergence

OM Babiker, I Bjerkebæk, A Xuan, L Shen… - Journal of Fluid …, 2023 - cambridge.org
In turbulence near a free surface, strong vortices attach to the surface, creating surface
imprints visible as nearly circular 'dimples'. By studying these imprints in direct numerical …

Effect of an incoming Gaussian wave packet on underlying turbulence

A Xuan, BQ Deng, L Shen - Journal of Fluid Mechanics, 2024 - cambridge.org
We present a simulation-based study of the effect of a passing wave packet on underlying
fully developed turbulence. We propose a novel wave-phase-resolved simulation method …

[HTML][HTML] Interactions between swell and colinear wind short crested waves, following and opposing

F Addona, M Clavero, L Chiapponi, S Longo - Coastal Engineering, 2025 - Elsevier
When wind blows over a water surface during a swell, it generates short-crested, three-
dimensional waves that interact with the underlying flow field through a mechanism that …

Evolution of wave characteristics during wind-wave generation

T Li, L Shen - arXiv preprint arXiv:2208.02489, 2022 - arxiv.org
The generation of ocean surface waves by wind is a classic fluid mechanics problem whose
theoretical study dates back to 1957, when the two seminal papers by Phillips and Miles …
