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…
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…
Experimental observations and modeling of sub-Hinze bubble production by turbulent bubble break-up
Daniel J. Ruth, Aditya K. Aiyer, Aliénor Rivière +2
We present experiments on large air cavities spanning a wide range of sizes relative to the Hinze scale , the scale at which turbulent stresses are balanced by surfac…
Capillary driven fragmentation of large gas bubbles in turbulence
A. Rivière, D. Ruth, W. Mostert +2
The bubble size distribution below a breaking wave is of paramount interest when quantifying mass exchanges between the atmosphere and oceans. Mass fluxes at the interface are driv…
