FLOW OF DILUTE POLYMER SOLUTIONS IN ROUGH PIPES

A simplified model is developed to describe the effects of boundary roughness on drag reduction achieved by polymer additives. The model is based on the assumption that the effect of the roughness is similar for flows with and without polymers, and can be used for both uniform and nonuniform roughness. Predictions of friction coefficients by means of the model are in reasonable agreement with experimental results.
