The Clauser plot: determine the value of the skin friction coefficient Cf by means of a curve fit of the law of the wall to (the lower part of) the velocity profile.
The Clauser plot The so–called Clauser–plot technique is used to determine the wall shear stress in a turbulent boundary layer from the mean velocity profile, in conditions where an accurate, direct determination of the velocity gradient at the wall is not possible (which is the common situation for turbulent boundary layers). The table given below … Read more
