文摘
- •
Bubbly flows are predicted using a two-fluid Eulerian–Eulerian CFD model.
- •
Evolution of the bubble diameter distribution is tracked using the Sγ model.
- •
Average bubble diameter radial profiles are successfully predicted.
- •
Coalescence and break-up significantly depend on the multiphase turbulence.
- •
Two bubble groups seem sufficient to describe the whole bubble diameter spectrum.
