ANALYSIS OF POSITION AND ROTATION DIRECTION OF DOUBLE STIRRER ON CHAOTIC ADVECTION BEHAVIOR

Turbulent mixing can damage the material molecules because of turbulence. Whereas laminar raises a problem when is carried out on viscous liquids. The mechanism using chaotic flow affects quality. aim experiment was to determine position and direction double stirrer mixer. installation mixer uses cylindrical tub two different mixers consisting primary (Pp) secondary (Ps). Periodically rotate container stirrer. center vessel are placed at same coordinates. For ?=4 cm (Pp Ps distance), there three experiments, namely: rotation directional (P2S-a), opposite (P2B-a), rotation, both stirrers variations. (P2V-a). Eccentricity 7 cm, also treatments as above: one (P2S-b), reverse (P2B-b), variation (P2V-b).
 video camera recordings processed digitally. Qualitative data show pattern behavior during mixing. Meanwhile, quantitative used level effectiveness. results showed that cylinders had no effect effectiveness Based number initial droplets dye, treatment experienced fastest chaos P2B-b, n=2 r=3.5303. difference in color does not affect behavior. highest efficiency generated by lowest P2V-b index value 0.94. Simultaneously, between will provide maximum efficiency. Isolated areas (island) poor occur one-way low eccentricity
