Sheared stratified turbulence driven by Kolmogorov flow
Alessandro Sozza, Andrea Maffioli
We investigate three-dimensional turbulence in a stably stratified fluid driven by a vertically sheared Kolmogorov flow using direct numerical simulations of the Boussinesq equatio…
Lagrangian irreversibility and energy exchanges in rotating-stratified turbulent flows
Sebastian Gallon, Alessandro Sozza, Fabio Feraco +2
Turbulence in stratified and rotating turbulent flows is characterized by an interplay between waves and eddies, resulting in continuous exchanges between potential and kinetic ene…
Instability of a dusty Kolmogorov flow
Alessandro Sozza, Massimo Cencini, Stefano Musacchio +1
Suspended particles can significantly alter the fluid properties and, in particular, can modify the transition from laminar to turbulent flow. We investigate the effect of heavy pa…
Drag enhancement in a dusty Kolmogorov flow
A. Sozza, M. Cencini, S. Musacchio +1
Particles suspended in a fluid exert feedback forces that can significantly impact the flow, altering the turbulent drag and velocity fluctuations. We study flow modulation induced…
Scalar absorption by particles advected in a turbulent flow
A. Sozza, M. Cencini, F. De Lillo +1
We investigate the effects of turbulent fluctuations on the Lagrangian statistics of absorption of a scalar field by tracer particles, as a model for nutrient uptake by suspended n…
Accumulated densities of sedimenting particles in turbulent flows
Alessandro Sozza, Gabor Drotos, Emilio Hernández-García +1
We study the effect of turbulence on a sedimenting layer of particles by means of direct numerical simulations. A Lagrangian model in which particles are considered as tracers with…
