There are rodlike micelle in surfactant solution occurring by turbulent frictional drag reduction. The theory about the behavior of the rodlike micelle is not elucidated. We focused attention on a recombination phenomenon and studied the theory model of the rodlike micelle and the network structure that rodlike micelle formed. The rodlike micelle was assumed as a rigid rod made up of beads that were lined up. Lennard-Jones potential and soft-sphere potential were employed as the inter-bead potentials for end-end beads and interior-interior beads, respectively. And we analyzed Brownian Dynamics Simulation. As a result, the micellar microstructures and the rheological properties of the surfactant solution at different shear and the first normal stress coefficient showed shear thinning characteristics. The relationship between the rheology and the microstructure of the surfactant solution was revealed. And the recombination phenomenon was seen.
