This paper describes an experimental investigation into the effect of riblets on the aerodynamic forces generated by sails. Riblets are known to reduce the viscous drag on flat surfaces and on airfoils, hut their effect on the drag-or on the lift -of a highly three-dimensional, very thin lifting sur
Numerical computations are reported of fully-developed flow through plane channels with knife-edge riblets. The study has covered riblet height: spacing ratios from 0.5 to 3 and riblet heights ranging from 0.1%-4.0% of the distance between the channel walls. In no case did results indicate a reducti
