ROTATION OF A DISK IN DILUTE POLYMER SOLUTIONS

Reduction in resistance to rotation of a disk in dilute, high-molecular-weight polymer solutions is calculated. The theoretical results, which are based on the assumption that the polymers increase the thickness of the viscous sublayer but leave the velocity defect law unaltered, are shown to be consistent with experimental data. The empirical coefficients that are related to the effect of the polymers on the thickness of the sublayer are found to be close to those measured in some pipe flows.
