May 23 2020&0183;&32;introduction you have already seen that the profile of time-average local fluid velocity (overlineu) from the bottom to the surface in turbulent flow down a plane is much blunter over most of the flow depth than the corresponding parabolic profile for laminar flow (figure 431)this is the place to amplify and quantify the treatment of velocity profiles in turbulent boundary-layer flows.
