Chemical Mixing Methods

Jun 22, 2017 · For larger mixing applications, pilot scale mixers can be used. However, with a larger bulk, and a greater bulk flow, in the reaction vessel, many larger scale mixers produce a laminar type flow rather than a turbulent flow which sometimes leads to problems in scaling-up a process due to the two scales having different mixing dynamics.
