ABSTRACT
Micromixing of Non-newtonian fluid in a stirred-tank reactor with
Rushton turbine is investigated numerically by using E model. It is
characterized by the product selectivity of parallel competitive
reactions. Model is implemented and is validated using experimental
data in the literature. The simulations show that a higher agitation
speed, and a feeding location closer to the discharge area of the
impeller favor micromixing and the reaction rate. These results
provide useful guidelines for the scale-up of industrial reactors of
non-Newtonian fluid with parallel chemical reactions, and the
comparison between the experimental and numerical results confirms
the accuracy of the simulations.
