Abstract
Owing to investigation of generation for flow-induced structure (FIS) of micellar solutions in an abrupt contraction and expansion flow, we observed the FIS of a rod-like micellar solution passing through a rectangular channel with a symmetric or asymmetric slit. Furthermore, liquid-temperature was changed as experimental conditions (relatively high-, room-, and low-temperature). For relatively high-temperature, a weak FIS exhibited in a symmetric slit-flow. For roomtemperature, agreement between the resultant FIS and the reported FIS was obtained. For relatively low-temperature, drastic FIS in upstream and slit section. In case of an asymmetric slit flow, the same tendency was obtained. However, profile of retardation was asymmetric in slit section. Moreover, degree of spatial constraint was discussed.
