The riblets impede the cross-stream translation of your streamwise vortices within the viscous sublayer. The mechanism is advanced and not nonetheless recognized fully. In essence, the riblets inhibit the vortex formation close to the surface area as the vortex are unable to fit in the valleys fashioned from the riblets. This pushes the vortex even more up within the surface, interacting only Using the riblet tips, not resulting in any higher-velocity stream in the valleys.
