5 cm in height (the total height of the inner cylinder is 4 cm) and centered at halfway of the cell. Reprinted from Lerouge et al. [195] amplitude (photo 12). Note that such different scattering properties in each band have also been reported in [153,157] using polarized SALS. The part of the stress dynamics corresponding to the appearance and the development of the interface instability is the small undershoot that precedes steady-state [195, 196]. A crucial point in this time sequence is that the small undershoot in the σ (t) curve appears as the mechanical signature of the interface instability.

1, the authors demonstrated that the position of the interface between bands strongly fluctuates as a function of time. The high shear rate band (light gray zone in Fig. 19) supports a roughly constant shear rate (γ˙ 70 s−1 ) and its width is strongly correlated to the degree of slip at the inner moving wall. The fluctuations are quasi-random or periodic, depending on sample preparation, and seem then to be driven by wall slip. A frequency analysis revealed that the correlation time ( 10 s) is of the same order of 36 S.

20 Map of the local shear rate γ˙(y,t) determined using USV, for a 20 wt. % C16 TAB/D2 O concentrated micellar system after start-up of flow at a fixed shear rate γ˙ = 50 s−1 in the banding regime. The extremum values of the gray scale are associated with γ˙ = 0 s−1 (black) and γ˙ > 120 s−1 (white). The positions y = 0 and y = 1 correspond, respectively, to the inner moving and outer fixed cylinders. The temperature is kept at 41◦ C. Reprinted with permission from Bécu et al. [172] magnitude as that observed in stress fluctuations.
