Euler-Euler Simulation of Bubbly Flow in Stirred Tanks


Euler-Euler Simulation of Bubbly Flow in Stirred Tanks

Rzehak, R.; Shi, P.

Aerated stirred tanks are frequently used equipment in industries ranging from chemical engineering and biotechnology to minerals processing. In principle, CFD simulation of such equipment on industrial scales is feasible within the Euler-Euler framework of interpenetrating continua. Practical application, however, requires suitable closure models to account for phenomena on the scale of individual bubbles, which are not resolved in this approach. Validation of such models is the purpose of the present contribution.

Keywords: aerated stirred tanks; dispersed gas-liquid multiphase flow; Euler-Euler two-fluid model; closure relations; Reynolds-stress turbulence model; CFD simulation
