In this study, we investigated mixing patterns of paddle impellers with two large blades in shear-thinning fluid by decoloring experiment and visualizing streak line. As a results, isolation mixing region like doughnut ring was observed in the upper side of MAXBLEND and Super-mix. On the other hand, that was observed in the center part of FULLZONE. By increasing Reynolds number, isolation mixing region like doughnut ring was quickly diminished. Streak line of MAXBLEND is also changed according to Reynolds number. Mixing patterns are changed according to Reynolds number, and mixing is improved by increasing Reynolds number.
