• In the present study, isolated mixing region in agitated vessel by use of paddle or disk-turbine impeller was visualized experimentally, and its structural property and formation mechanism were investigated in detail. A set of thin filaments spirally wrapping around the core of toroidal isolated mixing region is observed under laminar-flow conditions, which Reynolds number is smaller than 60. This filament rotates in both directions of horizontal and vertical circulating flows. Three-dimensional geometrical structure of filament in isolated mixing region depends on the periodical perturbations caused by the rotating impeller. We have succeeded in the determination of three-dimensional geometrical structure of filament in isolated mixing region based on the relation between the movement of fluid particle and filament numbers and/or wire turns. Interestingly, the wire turns of filaments are opposite to movements of fluid particles.
