Pseudo-laminarization of surfactant solutions in capillary flows

Wormlike micelle surfactant solutions showed turbulent drag reduction effects in pipe flows. It was well-known that SIS (Shear Induced Structure), reported in previous studies, made them. However, inner diameters (characteristic length) of pipes used in the previous studies were in the order of mill...
