文摘

Large-scale bubble column is simulated using the Eulerian multi-fluid approach. Validated set of closure models for the pseudo-homogeneous regime in a large-scale reactor. Fixed-poly-dispersed and poly-dispersed approach with bubble coalescence & break-up formulations are compared. Sensitivity analyses on velocity classes are performed. Sensitivity analyses on bubble size distribution at the inlet are performed.
