摘要：

We experimentally study the susceptibility to symmetry breaking of a closed turbulent von Karman swirling flow from Re 150 to Re similar or equal to 10(6). We report a divergence of this susceptibility at an intermediate Reynolds number Re = Re-chi similar or equal to 90 000 which gives experimental evidence that such a highly space and time fluctuating system can undergo a "phase transition.'' This transition is furthermore associated with a peak in the amplitude of fluctuations of the instantaneous flow symmetry corresponding to intermittencies between spontaneously symmetry breaking metastable states.
