Lagrangian chaos and the enstrophy cascade in Ekman-Navier-Stokes two-dimensional turbulence
Francesco Michele Ventrella, Victor de Jesus Valadão, Guido Boffetta +2
Two-dimensional turbulence with linear (Ekman) friction exhibits spectral properties that deviate from the classical Kraichnan prediction for the direct enstrophy cascade. In parti…

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…
