Using experimental data recorded in a low temperature helium jet, we have studied the statistics of velocity increments: Vr (x) = v(x +r) -v(x) conditioned on a "rate of energy transfer" anzatz, er : P(vr ]er). For a fixed value ofer, the histograms of Vr are found Gaussian at all scale, i.e. there
Fluctuating hydrodynamics, originally developed for fluctuations in fluids in equilibrium, can be extended to deal also with thermally excited hydrodynamic fluctuations in non-equilibrium states. After first reviewing some results earlier obtained for temperature fluctuations in fluids subjected to
