The CFD simulation for concentric draft tube airlift reactors with 3D analysis is developed in this study. The simulations were conducted for reactors considering two‐phase flow. Simulation of two reactors of different sizes and tube diameters is presented here for investigating the effect of tube diameter in gas hold‐up and velocities. The data which is obtained from the simulation is compared with the experimental data to determine the gas hold‐up. The comparison between gas hold‐up and superficial gas velocity was made and the velocities were set between 0.018 and 0.108.
