Numerical Simulation on Micromixing of Non Newtonian Fluids in a Stirred Tank Reactor by Using Parallel Reactions

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.
