Prise en compte des effets de la pression pour modéliser l'hydrodynamique et le transfert d'oxygène dans les colonnes à bulles à forte profondeur

International audience; A 1D-Model is developed to illustrate the sensitivity of simulations to processes and models proposed in literature to represent bubble size evolution and pressure effects on mass transfer. The proposed model can mimic experimental data of global gas hold-up and mass transfer coefficient in an experimental bubble column with a clear water/air system.
