Turbulence induces clustering and segregation of non-motile, buoyancy-regulating phytoplankton
Matteo Borgnino, Jorge Arrieta, Guido Boffetta +2
Turbulence plays a major role in shaping marine community structure as it affects organism dispersal and guides fundamental ecological interactions. Below oceanographic mesoscale d…
Effects of rotation on the bulk turbulent convection
Francesco Toselli, Stefano Musacchio, Guido Boffetta
We study rotating homogeneous turbulent convection forced by a mean vertical temperature gradient by means of direct numerical simulations (DNS) in the Boussinesq approximation in…
Condensate formation and multiscale dynamics in two-dimensional active suspensions
Moritz Linkmann, M. Cristina Marchetti, Guido Boffetta +1
The collective effects of microswimmers in active suspensions result in active turbulence, a spatiotemporally chaotic dynamics at mesoscale, which is characterized by the presence…
Gyrotactic phytoplankton in laminar and turbulent flows: a dynamical systems approach
Massimo Cencini, Guido Boffetta, Matteo Borgnino +1
Gyrotactic algae are bottom heavy, motile cells whose swimming direction is determined by a balance between a buoyancy torque directing them upwards and fluid velocity gradients. G…
Condensate in quasi two-dimensional turbulence
Stefano Musacchio, Guido Boffetta
We investigate the process of formation of large-scale structures in a turbulent flow confined in a thin layer. By means of direct numerical simulations of the Navier-Stokes equati…
Buoyancy-driven flow through a bed of solid particles produces a new form of Rayleigh-Taylor turbulence
G. Sardina, L. Brandt, G. Boffetta +1
Rayleigh--Taylor fluid turbulence through a bed of rigid, finite-size, spheres is investigated by means of high-resolution Direct Numerical Simulations (DNS), fully coupling the fl…
