Abstract
An Eulerian two fluid model (TFM) is coupled with the population balance method (PBM) for descriptions of gas-liquid flow in bubble columns with vertical internals. An improved bubble coalescence and breakup model is used in combination of the RNG k- turbulence model and the inter-phase interactions including the drag force and the lift force. A radial wall lubrication force is implemented into the simulation model to take into account the effect of internal walls. The model is validated against literature data in terms of gas holdup and the bubble size distributions. When the internals are present, the turbulent dissipation rates increase significantly in the gaps between the internal walls, and more bubbles with smaller bubble size are predicted in bubble column.
