Gyrotactic swimmers in turbulence: shape effects and role of the large-scale flow
Matteo Borgnino, Guido Boffetta, Filippo De Lillo +1
We study the dynamics and the statistics of dilute suspensions of gyrotactic swimmers, a model for many aquatic motile microorganisms. By means of extensive numerical simulations o…
Scaling of Rayleigh-Taylor mixing in porous media
G. Boffetta, M. Borgnino, S. Musacchio
Pushing two fluids with different density one against the other causes the development of the Rayleigh-Taylor instability at their interface, which further evolves in a complex mix…
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…
Alignment of non-spherical active particles in chaotic flows
M. Borgnino, K. Gustavsson, F. De Lillo +3
We study the orientation statistics of spheroidal, axisymmetric microswimmers, with shapes ranging from disks to rods, swimming in chaotic, moderately turbulent flows. Numerical si…
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…
