Characterization of turbulence in inhomogeneous anisotropic flows (2008)
Cortet, Pierre-Philippe, Diribarne, Pantxo, Monchaux, Romain, Chiffaudel, Arnaud, Daviaud, Francois, Dubrulle, Berengere
We introduce a global quantity $\delta$ that characterizes turbulent fluctuations in inhomogeneous anisotropic flows. This time-dependent quantity is based on spatial averages of global velocity...
Supercritical transition to turbulence in an inertially-driven von Karman closed flow (2008)
Ravelet, Florent, Chiffaudel, Arnaud, Daviaud, Francois
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 blades over a wide...

Supercritical transition to turbulence in an inertially-driven von Karman closed flow (2006)
Ravelet, Florent, Chiffaudel, Arnaud, Daviaud, Francois
We study the transition from basic state to fully developed turbulence for an inertially-driven von Karman flow between two counter-rotating large impellers fitted with curved blades. The laminar...
Ravelet, Florent, Marie, Louis, Chiffaudel, Arnaud, Daviaud, Francois
We report an experimental evidence of a global bifurcation on a highly turbulent von Karman flow. The mean flow presents multiple solutions: the canonical symmetric solution becomes marginally...
Garnier, Nicolas, Chiffaudel, Arnaud, Daviaud, Francois, Prigent, Arnaud
We present experimental results on hydrothermal traveling-waves dynamics in long and narrow 1D channels. The onset of primary traveling-wave patterns is briefly presented for different fluid heights...
Garnier, Nicolas, Chiffaudel, Arnaud, Daviaud, Francois
We present experimental results on hydrothermal waves in long and narrow 1D channels. In a bounded channel, we describe the primary and secondary instabilities leading to waves and modulated waves in...
Convective and absolute Eckhaus instability leading to modulated waves in a finite box (2002)
Garnier, Nicolas, Chiffaudel, Arnaud, Daviaud, Francois
We report experimental study of the secondary modulational instability of a one-dimensional non-linear traveling wave in a long bounded channel. Two qualitatively different instability regimes...
Bekki-Nozaki Amplitude Holes in Hydrothermal Nonlinear Waves (1999)
Burguete, Javier, Chate, Hugues, Daviaud, Francois, Mukolobwiez, Nathalie
We present and analyze experimental results on the dynamics of hydrothermal waves occuring in a laterally-heated fluid layer. We argue that the large-scale modulations of the waves are governed by a...
