Diffusion of turbulence following both stable and unstable step stratification perturbations
Luca Gallana, Shahbozbek Abdunabiev, Mina Golshan +1
The evolution of a two-phase, air and unsaturated water vapor, time decaying, shearless, turbulent layer has been studied in the presence of both stable and unstable perturbations…
Wave focusing and related multiple dispersion transitions in plane Poiseuille flows
Federico Fraternale, Gabriele Nastro, Daniela Tordella
Motivated by the recent discovery of a dispersive-to-nondispersive transition for linear waves in shear flows, we accurately explored the wavenumber-Reynolds number parameter map o…
Intermittency acceleration of water droplet population dynamics inside the interfacial layer between cloudy and clear air environments
Mina Golshan, Shahbozbek Abdunabiev, Mattia Tomatis +3
We use direct numerical simulation to study the temporal evolution of a perturbation localized on the turbulent layer that typically separates a cloud from the surrounding clear ai…
Linear waves in sheared flows. Lower bound of the vorticity growth and propagation discontinuities in the parameters space
Federico Fraternale, Loris Domenicale, Gigliola Staffilani +1
This study provides sufficient conditions for the temporal monotonic decay of enstrophy for two-dimensional perturbations traveling in the incompressible, viscous, plane Poiseuille…
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…
Energy and water vapor transport across a simplified cloud-clear air interface
Luca Gallana, Silvio Di Savino, Francesca De Santi +2
We consider a simplified physics of the could interface where condensation, evaporation and radiation are neglected and momentum, thermal energy and water vapor transport is repres…
