Orientational turbulence. Each line is a wall separating domains where the molecules have different orientations:
When the rotary motion of one plate is stopped, the turbulent state melts in a similar way as it was constituted of ice blocks melting in liquid water:
The remaining droplets serve as seeds for a new starting shear motion: Single domains will disappear but double ones will grow with their characteristic shape:
Between crossed polarizers, the differently oriented domains are made visible:
a) without polarizers
b) with polarizers
