Abstract
In this work we present a study of intermittency in a channel, i.e. in a non-homogeneous, non-isotropic flow. Scaling exponents of longitudinal stream-wise structure functions, ζ p , are used as quantitative indicators of intermittency. We find that, near the core of the channel, the value of ζ p are consistent with homogeneous/isotropic values. Near the boundaries intermittency is much higher approaching passive scalar values.
