Bandyopadhyay, Ranjini and Basappa, Geetha and Sood, AK (2000) Observation of Chaotic Dynamics in Dilute Sheared Aqueous Solutions of CTAT. In: Physical Review Letters, 84 (9). 2022 -2025.
The nonlinear flow behavior of a viscoelastic gel formed due to entangled, cylindrical micelles in aqueous solutions of the surfactant cetyl trimethylammonium tosilate (CTAT) has been studied. On subjecting the system to a step shear rate lying above a certain value, the shear and normal stresses show interesting time dependent behavior. The analysis of the measured time series shows the existence of a finite correlation dimension and a positive Lyapunov exponent, unambiguously implying that the dynamics can be described by that of a dynamical system with a strange attractor whose dimension increases with the increase in shear rate.
