# Global effect of local skin friction drag reduction in spatially developing turbulent boundary layer

@article{Stroh2016GlobalEO, title={Global effect of local skin friction drag reduction in spatially developing turbulent boundary layer}, author={Alexander Stroh and Yosuke Hasegawa and Philipp Schlatter and Bettina Frohnapfel}, journal={Journal of Fluid Mechanics}, year={2016}, volume={805}, pages={303 - 321} }

A numerical investigation of two locally applied drag-reducing control schemes is carried out in the configuration of a spatially developing turbulent boundary layer (TBL). One control is designed to damp near-wall turbulence and the other induces constant mass flux in the wall-normal direction. Both control schemes yield similar local drag reduction rates within the control region. However, the flow development downstream of the control significantly differs: persistent drag reduction is found…
