Bifurcations of a large scale circulation in a quasi-bidimensional turbulent flow
Guillaume Michel, Johann Herault, François Pétrélis +1
We report the experimental study of the bifurcations of a large-scale circulation that is formed over a turbulent flow generated by a spatially periodic forcing. After shortly desc…
1/f noise in turbulent flows
Johann Herault, François Pétrélis, Stephan Fauve
We report the experimental observation of fluctuations in three different turbulent flow configurations: the large scale velocity driven by a two-dimensional turbulent flow,…
Decay rates of magnetic modes below the threshold of a turbulent dynamo
Johann Herault, François Pétrélis, Stephan Fauve
We measure the decay rates of magnetic field modes in a turbulent flow of liquid sodium below the dynamo threshold.We observe that turbulent fluctuations induce energy transfers be…
Reversals of a large scale field generated over a turbulent background
Basile Gallet, Johann Herault, Claude Laroche +2
We present a study of several systems in which a large scale field is generated over a turbulent background. These large scale fields usually break a symmetry of the forcing by sel…
