文摘
- •
Transient velocity fluctuations are measured for shear banded wormlike micelles.
- •
Bands of variable velocities are generated near the wall along the vorticity axis.
- •
Dynamics are observed for applied shear rates near the shear band onset value.
- •
Flow variations are temporary and homogeneous flow is observed at steady-state.
