Stabilization of the Rayleigh-Bénard system by injection of thermal inertial particles and bubbles
Saad Raza, Silvia C. Hirata, Enrico Calzavarini
The effects of a dispersed particulate phase on the onset of Rayleigh-Bénard convection in a fluid layer is studied theoretically by means of a two-fluid Eulerian modelization. The…
Impact of ageostrophic dynamics on the predictability of Lagrangian trajectories in surface-ocean turbulence
Michael Maalouly, Guillaume Lapeyre, Stefano Berti
Turbulent flows at the surface of the ocean deviate from geostrophic equilibrium on scales smaller than about 10 km. These scales are associated with important vertical transport o…
Particle dispersion and clustering in surface ocean turbulence with ageostrophic dynamics
Michael Maalouly, Guillaume Lapeyre, Bastien Cozian +2
Upper-ocean turbulent flows at horizontal length scales smaller than the deformation radius depart from geostrophic equilibrium and develop important vertical velocities, which are…
Convective heat transfer in the Burgers-Rayleigh-Bénard system
Enrico Calzavarini, Silvia C. Hirata
The dynamics of heat transfer in a model system of Rayleigh-Bénard (RB) convection reduced to its essential, here dubbed Burgers-Rayleigh-Bénard (BRB), is studied. The system is sp…
Sea Water Freezing Modes in a Natural Convection System
Yihong Du, Ziqi Wang, Linfeng Jiang +2
Sea ice is crucial in many natural processes and human activities. Understanding the dynamical couplings between the inception, growth and equilibrium of sea ice and the rich fluid…

We study the translational and rotational dynamics of neutrally-buoyant finite-size spheroids in hydrodynamic turbulence by means of fully resolved numerical simulations. We examin…
Three-dimensional turbulence effects on plankton dynamics behind an obstacle
Alice Jaccod, Stefano Berti, Enrico Calzavarini +1
We study a predator-prey model of plankton dynamics in the two and three-dimensional wakes of turbulent flows behind a cylinder, focusing on the impact of the three-dimensional cha…
Effects of large-scale advection and small-scale turbulent diffusion on vertical phytoplankton dynamics
Vinicius Beltram Tergolina, Enrico Calzavarini, Gilmar Mompean +1
Turbulence has been recognized as a factor of paramount importance for the survival or extinction of sinking phytoplankton species. However, dealing with its multiscale nature in m…
Equilibrium states of the ice-water front in a differentially heated rectangular cell
Ziqi Wang, Enrico Calzavarini, Chao Sun
We study the conductive and convective states of phase-change of pure water in a rectangular container where two opposite walls are kept respectively at temperatures below and abov…
Predator-prey plankton dynamics in turbulent wakes behind islands
Alice Jaccod, Stefano Berti, Enrico Calzavarini +1
Plankton constitutes the productive base of aquatic ecosystems and plays an essential role in the global carbon cycle. The impact of hydrodynamic conditions on the biological activ…
