Summary
Measurements in turbulent channel flow subjected to small periodic velocity oscillations are reported. The mean flow and the mean turbulent intensity are not affected by the forced oscillations. The periodic oscillations follow closely the laminar Stokes solution near the wall, except a low frequency where the phase shift tends to zero. It is shown that the non dimensional Stokes thickness ℓ +s in terms of the wall thickness is the important parameter.
