Numerical Investigation on the Stirred Reactor with Rushton Turbine

Computational Fluid Dynamics (CFD) simulation is expected to give detailed flow information which is important for stirred reactor design and optimization, however accurate flow prediction remains a challenge for CFD application. In the present paper, influence of discretization scheme on the flow prediction in a stirred reactor with Rushton turbine was investigated. Standard k-e turbulent model and MRF model was adopted and numerical results obtained by using three different discretization schemes were compared. Results showed that the numerical results agreed well with data provided in literature. It is acceptable to use any discreticaiton method if aiming at a general flow field, while QUICK is recommended considering the more detailed flow information.
