This paper deals with some of the features that distinguish wall-bounded sheared turbulence from that in free-shear flows. It concerns itself mostly with the largest structures at each wall distance, because they are where energy is fed into the fluctuations, and therefore the ones that differ most between the different flows. Because of the geometric limitations imposed by the wall, the largest scales roughly coincide with the smallest ones in the viscous buffer layer, but the rest of the flow is characterised, as in most turbulent cases, by a wide range of scales. © 2010 Springer-Verlag Berlin Heidelberg.
