### Abstract

Significant progress has been made towards understanding the large scale features of wall-bounded shear flow in zero pressure gradient (ZPG) turbulent boundary layers (TBL). Here we consider their effects in adverse pressure gradient (APG) flows where the pressure gradient parameter is held constant and Reynolds number is varied. This is done by documenting the changes in the mean velocity, streamwise turbulence intensities and their associated spectral densities. Increased large-scale activity near the wall is seen with increasing Reynolds number and for this pressure gradient, the mean flow deviates from the classically regarded log-law.
