Li, W. Jessen, W. Klaas, M. Schröder, W. Abstract The influence of spanwise traveling transversal surface waves on the near-wall flow field of turbulent boundary layers with and without adverse pressure gradient is investigated by particle-image velocimetry (PIV) and micro-particle tracking velocimetry (μ-PTV). A detailed analysis of the velocity profile immediately downstream of the actuated surface shows a local drag decrease as well as an increase caused by the surface wave dependent on the wave parameters.
