DOI: 10.1007/s10652-024-09978-w
Abstract: In high-velocity free-surface flows, the interactions between the fast-flowing flow and the atmosphere can lead to strong air–water mixing through the free-surface. The flow resistance may be derived from momentum and energy considerations. This was… read more here.

DOI: 10.1063/5.0278589
Abstract: This study investigates turbulence modeling in free-surface flows, with a focus on wave-driven turbulence and wave–structure interactions (WSI). The work examines the interplay between high-shear turbulence during breaking waves and low-turbulence regions under non-breaking waves.… read more here.
