The Influence of the Chemical Nature of Polymers on Their Drag Reduction Characteristics.
Abstract
The influence of the chemical nature of polymers on their drag reduction characteristics was investigated for four different compounds, two commercially available Polyacrylamide (PAM) Polystyrene sulfonate (PSS) and two laboratory modifications of PAM. The degradation of these polymers under repeated shear was also investigated It is concluded that, by properly tailoring the structural changes of the polymer molecules, higher drag reductions with less degradation can be obtained. Finally, the results of a screening investigation on the drag-reduction characteristics of starches and starch derivatives are presented. It is concluded that these natural resins do not display drag-reducing properties. (Author)
