Thermal behaviour of settling heavy inertial particles in turbulent natural convection
Hamid Reza Zandi Pour, Guido Boffetta, Stefano Musacchio +1
We investigate the dynamical and thermal behaviour of settling heavy inertial particles in bulk turbulent thermal convection. Direct numerical simulations are performed in a homoge…
Scaling and Predictability in Surface Quasi-Geostrophic Turbulence
V. J. Valadão, F. De Lillo, S. Musacchio +1
Turbulent flows are strongly chaotic and unpredictable, with a Lyapunov exponent that increases with the Reynolds number. Here, we study the chaoticity of the Surface Quasi-geostro…
Manipulating the direction of turbulent energy flux via tensor geometry in a two-dimensional flow
Xinyu Si, Filippo De Lillo, Guido Boffetta +1
In turbulent flows, energy flux refers to the transfer of kinetic energy across different scales of motion, a concept that is a cornerstone of turbulence theory. The direction of n…
Modeling straight and circle swimmers via immersed boundary methods: from single swimmer to collective motion
Francesco Michele Ventrella, Guido Boffetta, Massimo Cencini +1
We propose a minimal model of microswimmer based on immersed boundary methods. We describe a swimmer (either pusher or puller) as a distribution of point forces, representing the s…
Microswimmer trapping in surface waves with shear
Francesco Michele Ventrella, Nimish Pujara, Guido Boffetta +3
Many species of phytoplankton migrate vertically near the surface of the ocean, either in search of light or nutrients. These motile organisms are affected by ocean waves at the su…
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…
