Velocity gradients statistics along particle trajectories in turbulent flows: the refined similarity hypothesis in the Lagrangian frame
Roberto Benzi, Luca Biferale, Enrico Calzavarini +2
We present an investigation of the statistics of velocity gradient related quantities, in particluar energy dissipation rate and enstrophy, along the trajectories of fluid tracers…

Fluctuation-Dissipation Relations and statistical temperatures in a turbulent von Kármán flow
Romain Monchaux, Pierre-Philippe Cortet, Pierre-Henri Chavanis +4
We experimentally characterize the fluctuations of the non-homogeneous non-isotropic turbulence in an axisymmetric von Kármán flow. We show that these fluctuations satisfy relation…
