Diffusion of gravity waves by random space inhomogeneities in pancake-ice fields. Theory and validation with wave buoys and synthetic aperture radar
Piero Olla, Giacomo De Carolis, Francesca De Santi
We study the diffusion of ocean waves by ice bodies much smaller than a wavelength, such as pancakes and small ice floes. We argue that inhomogeneities in the ice cover at scales c…
Limit regimes of ice formation in turbulent supercooled water
Francesca De Santi, Piero Olla
A study of ice formation in stationary turbulent conditions is carried out in various limit regimes of crystal growth, supercooling and ice entrainment at the water surface. Analyt…
Effect of small floating disks on the propagation of gravity waves
Francesca De Santi, Piero Olla
A dispersion relation for gravity waves in water covered by disk-like impurities embedded in a viscous matrix is derived. The macroscopic equations are obtained by ensemble-averagi…
Dispersive to non-dispersive transition and phase velocity transient for linear waves in plane wake and channel flows
Francesca De Santi, Federico Fraternale, Daniela Tordella
In this study we analyze the phase and group velocity of three-dimensional linear traveling waves in two sheared flows, the plane channel and the wake flows. This was carried out b…
New observations in transient hydrodynamic perturbations. Frequency jumps, intermediate term and spot formation
Stefania Scarsoglio, Francesca De Santi, Daniela Tordella
Sheared incompressible flows are usually considered non-dispersive media. As a consequence, the frequency evolution in transients has received much less attention than the wave ene…
Kolmogorov scaling bridges linear hydrodynamic stability and turbulence
Stefania Scarsoglio, Francesca De Santi, Daniela Tordella
The way in which kinetic energy is distributed over the multiplicity of inertial (intermediate) scales is a fundamental feature of turbulence. According to Kolmogorov's 1941 theory…
