| Summary, etc. |
An important practical aspect in the application and study of drag reduction by polymer additives is the degradation of the polymer, for instance due to intense shearing, especially in circulatory flow systems. Such degradation leads to a marked loss of the drag-reducing capability of the polymer. Polymers-Surfactant complex efficacy in reducing the drag and improving the degradation resistance is a new subject in drag reduction research. Turbulent drag reduction (DR) efficacy of ionic Sodium Polystyrene Sulfonate (NaPSS) and sodium Alkylbenzene sulfonate, complexes systems regarding polymer-surfactant interaction was examined under a turbulent flow in a rotating disk apparatus, in which the DR efficacy indicates how the torque is being reduced with a tiny amount of additives under a turbulent flow at a fixed rotational speed. It was found that the addition of the surfactant to the ionic increased the polymer chain dimensions via a conformational structural change, thus enhancing the DR efficacy. Polymer–surfactant system also shows that there exists a critical polymer concentration at which the drag reduction becomes a maximum, and then above the critical concentration, the DR efficacy decreases more rapidly than that of pure polymeric systems. On the other hand, it was found that the addition of the surfactant to the ionic polymer enhance its ability to resist the degradation caused by the high shear stress in the eddy flow. The addition of sodium Alkylbenzene sulfonate to the ionic polymer was found to have higher improvement than the addition of DDAB in degradation resistance. The DR and degradation resistance efficacy induced by the polymer-surfactant mixture is found to be obvious higher than of pure polymer. In addition, the maximum of DR efficacy versus polymer concentration occurred at 700 ppm. |
