FLOW OF DILUTE POLYMER SOLUTIONS IN ROUGH PIPES,

Abstract

A simplified model is developed to describe the effects of boundary roughness on drag reduction achieved by polymer additives. The model is suitable for both uniform and nonuniform roughness. Predictions of friction coefficients by means of the model are in reasonable agreement with experimental results. (Author)
