Long rigid fibres in a turbulent channel flow: comparison between experiments and simulations
Defa Sun, Florian Zumbo, Christophe Pitiot +4
The dynamics of long rigid fibres transported by turbulent channel flow are investigated experimentally and numerically. Experiments use polystyrene fibres of three lengths, $\ell/…

Harnessing swarms for directed migration of interacting active particles via optimal global control
Chiara Calascibetta, Laëtitia Giraldi, Jérémie Bec
This study investigates the use of global control strategies to enhance the directed migration of swarms of interacting self-propelled particles confined in a channel. Uncontrolled…

Surface quasigeostrophic turbulence: The refined study of an active scalar
Nicolas Valade, Jérémie Bec, Simon Thalabard
SQG describes the 2D active transport of a scalar field, such as temperature, which -- when properly rescaled -- shares the same physical dimension of length/time as the advecting…
