Turbulence control techniques are of great economical and ecological interest. In the present work a fundamental study is carried out in which body forces are introduced in the near-wall region of a turbulent channel flow and thus modify the near-wall behavior. It is investigated how these forces, which selectively act on one of the velocity components, modify near-wall turbulence and its statistical properties with the goal to extract properties that can directly be linked to the skin friction drag. The alignment between the principal axis of the Reynolds stress tensor and the mean flow direction is identified as an interesting quantity in this respect.
