Abstract

The onset of drag reduction is observed in a 0.635 cm (0.25 in.) turbulent pipe flow for dilute solutions of Polyox WSR N-80 in three different glycerine-water solutions. The time scale onset hypothesis is found to be much more consistent with the data than the length scale onset hypothesis.
