CFD Simulation of Stirred Vessel Reactors
CFD simulations of a mixing sensitive reaction process, carried out in a stirred vessel and consisting of two parallel second order reactions competing for a common reagent, axe performed. The different discretization needs of the process simulation with respect to the fluid-dynamics simulation axe addressed and exploited to conveniently conduct the former with a much coarser gridding. Simulation results are compared with in-house experimental data and a good agreement is observed. No micromixing modelling is found to be required in order to match simulations and experiment, even when the common reagent is slowly injected in the premixed solution containing the other two reagents.
