Abstract
A number of investigators have attributed the reduced turbulent flow drag exhibited by polymer solutions to their high elongational viscosity. The results of a recent theoretical study of drag reduction are summarized, which show that it may instead be a consequence of the non-Newtonian behavior of polymer solutions in time-varying shear fields. Experiments are proposed to ascertain the relative importance of these transient shear effects and elongational effects in reducing drag.
