Two different scenarios based on single and dual off-centered impellers were proposed and compared to the standard steady-stirring configuration.
Mixing times were experimentally measured by means of a color-discoloration technique based on a fast acid-base reaction, which allowed also revealing the formation of well-mixed zones (pseudocaverns) as well as segregated regions.
The finite element method (FEM) was used for modeling the mixing tank w...
