Characterization of turbulence in inhomogeneous anisotropic flows
Pierre-Philippe Cortet, Pantxo Diribarne, Romain Monchaux +3
We introduce a global quantity that characterizes turbulent fluctuations in inhomogeneous anisotropic flows. This time-dependent quantity is based on spatial averages of global…
Euler-like modelling of dense granular flows: application to a rotating drum
Daniel Bonamy, Pierre-Henri Chavanis, Pierre Philippe Cortet +3
General conservation equations are derived for 2D dense granular flows from the Euler equation within the Boussinesq approximation. In steady flows, the 2D fields of granular tempe…
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…
Supercritical transition to turbulence in an inertially-driven von Karman closed flow
Florent Ravelet, Arnaud Chiffaudel, Francois Daviaud
We study the transition from laminar flow to fully developed turbulence for an inertially-driven von Karman flow between two counter-rotating large impellers fitted with curved bla…
