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
The frequency response of the concentration boundarylayer is often a concern when flush mounted mass transfer probes are used to measure turbulent fluctuations in the velocity gradient at a wall. Present practice involves the use of a solution of the mass balance equation which is linear in the fluc
