DESCRIPTION:Abstract: Riblets are a surface texture composed of tiny ribs 
 applied on aircraft skin to reduce drag\, which saves fuel\, increases pay
 load and reduces emissions. To the fast-moving turbulent air that flows ov
 er it\, riblets turn out to be smoother\, generating less skin friction\, 
 than a perfectly flat surface. However\, riblet performance is highly sens
 itive to their cross-sectional shape and features\, which is bad news beca
 use the micron-sized ribs\, imperceptible to the naked eye and challenging
  to measure even with precision instruments\, are impossible to manufactur
 e and maintain perfectly. Thus\, accurate tolerancing\, not only for manuf
 acture but also for lifetime wear planning and monitoring\, is key to this
  technology\, requiring predictive capability of the kind that derives fro
 m advances in basic understanding. In this regard\, I will present some of
  the progress we have made in the last few years\, building on decades of 
 research\, on the fluid mechanics of turbulence over riblet surfaces.\n\nh
