文摘
- •
Simplified volume-averaged models are rigorously derived.
- •
The behavior of a realistic liquid–liquid stirred tank is considered.
- •
The results are compared with those obtained with a rigorous 3D CFD-PBM model.
- •
0D “homogeneous” model can be used when the DSD is spatially uniform.
- •
Appropriate approach can be determined a priori with a time scale analysis.
