Dynamo regimes and transitions in the VKS experiment
M. Berhanu, G. Verhille, J. Boisson +14
The Von K{á}rm{á}n Sodium experiment yields a variety of dynamo regimes, when asymmetry is imparted to the flow by rotating impellers at different speed F1 and F2. We show that as…
Susceptibility divergence, phase transition and multistability of a highly turbulent closed flow
P. -P. Cortet, E. Herbert, A. Chiffaudel +3
Using time-series of stereoscopic particle image velocimetry data, we study the response of a turbulent von Kármán swirling flow to a continuous breaking of its forcing symmetry. E…
Experimental evidence of a phase transition in a closed turbulent flow
P. -P. Cortet, A. Chiffaudel, F. Daviaud +1
We experimentally study the susceptibility to symmetry breaking of a closed turbulent von Kármán swirling flow from to . We report a divergence of this…
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…
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…
