Hydrodynamic and mass transfer characteristics of an annulus-rising airlift reactor (AR_ALR) were investigated with experimental and CFD simulation methods. A three-phase Eulerian model was developed to simulate the AR_ALR in three flow regimes. 3D steady state CFD simulations were performed under different gas superficial velocities (Ug). Good agreements on gas holdup and volumetric mass transfer coefficient were obtained over the range of the studied Ug. The three flow regimes in AR_ALR were captured well and are similar to those observed in experiments. The developed CFD model can be used to predict mass transfer and gas holdup in AR_ALRs at different scales
