RIBLETS IN FULLY DEVELOPED TURBULENT CHANNEL FLOW
This database features high-precision pressure drop and flow rate measurements in an air channel flow facility with aspect ratio 1:12 which were taken to determine the skin friction drag reduction of riblets. The dataset includes values for the smooth wall reference case and three geometrically different sets of riblets. Multiple flow rate measurement devices are used (see table1), namely an inlet nozzle and an orifice flow meter. The measurements were taken by Andreas Güttler, Lars von Deyn and Luigi Coppini.
