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/…

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…
