The Bubble Breakage Effects on Hydrodynamics of Bubble Column Reactor by CFD Techniques

Gas-liquid flow in a cylindrical bubble column was simulated with a 2D steady state CFD model. The importance of using the bubble population balance model for such simulations was illustrated. In order to make the model better, different turbulence models (RNG and standard k- model),interpolating schemes (second and first order upwind), and variety of bubble diameters wereexamined and compared. The best agreement with experimental data was captured by using theRNG k- turbulence model, second order upwind and population balance approach. The model predicted the mean bubble diameter radial profile which confirms the experimental observations
