Detailed experiments have been conducted to investigate the effect of adverse pressure gradients on the log-law in turbulent boundary layers. The wall shear stress was measured by a direct measurement device and the scaling law of the mean velocity was discussed based on high-accuracy experimental data. Considering the significant contribution of the inertia term in the equations of motion, a new velocity scale is defined and a similarity law was obtained for the mean velocity profile subjected to an adverse pressure gradient.
