Abstract: The simulation of two-phase flow in bubble columns using commercially available software from Fluent Incorporated is presented here. Data from a bubble column with a ratio of height to the column diameter of 5 : 1 are compared with simulations and experimental results for time-averaged velocity and Reynolds stress profiles are used to validate transient, two-dimensional simulations. The models are based on multiphase biological reactors with applications in the food industry. An example case of the mass transfer of oxygen through the liquid phase is also presented.
