Abstract
The main of this paper is verify previously data in CFD simulations of hydrodynamics internal loop airlift reactors. The CFD simulation were done in commercial code CFX 17.2 using the Euler-Euler model for multiphase flow and boundaries conditions in accordance with the literature. Gas superficial velocities in riser were in range from 0,01 to 0,075 m/s. The simulation was done to study the global flow characteristics as air holdup and liquid interstitial velocity in the riser and downcomer. The results are in agreement with those obtained in literature except at the highest surface velocity of the gas where all results are underestimated.
