Alignment of elongated swimmers in a laminar and turbulent Kolmogorov flow
M. Borgnino, G. Boffetta, M. Cencini +2
Many aquatic microorganisms are able to swim. In natural environments they typically do so in the presence of flows. In recent years it has been shown that the interplay of swimmin…
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…
Scale-dependent co-localization in a population of gyrotactic swimmers
Matteo Borgnino, Filippo De Lillo, Guido Boffetta
We study the small scale clustering of gyrotactic swimmers transported by a turbulent flow, when the intrinsic variability of the swimming parameters within the population is consi…
