Investigation of hydrodynamics of the gas-liquid flow in the internal airlift reactor with different velocities and two different configuration using CFD

The main objective of the present paper is to simulation of the hydrodynamics of the internal airlift reactor(ALR) for two configuration and different velocities. Special attention has been paid on the liquid circulation velocity and the liquid velocity in the riser. comutational fluid dynamics(CFD) tools are used for modeling results. Modeling results are compared with the experimental data. The CFD modeling results show excellent agreement with the experimental data on gas hold up and liquid velocity in the riser.
