Use of the turbulent drag correction and the population balance model in gas-liquid flow modelling using CFD
Original language description
The main topic of this study is the experimental measurement and mathematical modelling of global gas hold-up and bubble size distribution in an aerated stirred vessel using the CFD (Computational Fluid Dynamics) method. The air-water system consisted ofa mixing tank of diameter T = 0.29 m, which was equipped with a six-bladed Rushton turbine. Calculations were performed with the CFD software CFX 12.1. The turbulent quantities were predicted using the standard k-epsilon turbulence model and the rotating impeller was modelled via the MRF method. Coalescence and breakup of bubbles were modelled using the homogeneous MUSIG method with 13 bubble size groups. Several different drag coefficient correlations were implemented in the solver, and their influence on the results was studied. Turbulent drag correction to reduce the bubble slip velocity proved to be essential to achieve agreement of the simulated gas distribution with experiments.
