The riblets impede the cross-stream translation of the streamwise vortices within the viscous sublayer. The mechanism is sophisticated and not still comprehended fully. Basically, the riblets inhibit the vortex development near the surface because the vortex can't slot in the valleys formed with the riblets. This pushes the vortex even further up from the area, interacting only Using the riblet tips, not causing any higher-velocity flow during the valleys.
