Abstract

"Turbulent velocity profiles in viscoelastic drag reducing solutions were measured using hot-film anemometer and Pitot tube techniques. Data were obtained in a solution of one per cent aluminium [sic] dioleate in toluene and in 0.2 and 0.4 per cent solutions of polyisobutylene (PIB) L-200 in cyclohexane. Velocity profiles were also obtained for comparison in toluene and cyclohexane by both techniques. By integrating the Pitot tube velocity profiles, large flow rate discrepancies between integrated and measured flow rates were found for the drag reducing polymer and soap solutions. This discrepancy was not observed in the hot-film anemometer measurements. The hot-film anemometer results indicated flatter profiles for the drag reducing soap solutions and steeper profiles for the drag reducing polymer solutions compared with the solvents. A plot of the anemometer data at the highest Reynolds numbers in the form of u⁺ versus log y⁺ indicated an increase of thickness in the boundary layer for both soap and polymer solutions"--Abstract, page 1.
