Abstract
The measurements of the rheological properties of quaternary ammonium salt cationic surfactant solutions were carried out by means of a cone-plate rheometer and a capillary viscometer. Experimental results showed a non-linear shear stress-shear rate relationship over a wide range of shear rates. Combined with the damping factor model for viscoelastic fluids, the non-linear viscosity relationship was successfully used to predict the turbulent flow characteristics in a drag-reducing surfactant flow.
