摘要：
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 streamwise structure functions, zeta(p), are used as quantitative indicators of intermittency. We find that, near the core of the channel, the value of zeta(p) are consistent with homogeneous/isotropic values. Near the boundaries intermittency is much higher approaching passive scalar values.
