“…PBM is an effective method to calculate BSD for gas-liquid flows on the condition that bubble coalescence and breakup models are provided as model closures. Many researchers have used the coupled CFD-PBM model to predict the hydrodynamics and mass transfer in multiphase reactors [9][10][11][12][13][14]. Their studies showed that a better agreement between simulations and experiments was obtained when BSD was considered compared to using a constant mean bubble diameter.…”

“…Xing et al [14] investigated the ability of the CFD-PBM coupled model to account for the effect of viscosity on the gas holdup in a bubble column. The feature that the increased viscosity resulted to a decrease in the volume fraction of small bubbles and an increase in the volume fraction of large bubbles was captured well using the developed CFD-PBM model [12,15]. The coupled CFD-PBM simulations of ALR are relatively rare, especially with the viscous or non-Newtonian fluid.…”

“…The potential of Computational Fluid Dynamics (CFD) for describing the hydrodynamics of bubble column has been established by several publications in the past (Baten and Krishna, 2005; Wang and Wang, 2007). What happens quantitatively, when fluids flow, how fluid flow, how are the velocity vectors, how the pressure contours are predicted by the CFD simulations.…”

“…The models used for numerical simulations of the gas-liquid two-phase flow in bubble columns mainly include the Euler-Euler two-fluid model [5], Euler-Euler two-fluid model coupled with a population balance model (PBM) [6][7][8] and discrete particle model (DPM) [4]. The PBM accounts for the effects of bubble coalescence and breakup and can predict the local bubble size distribution [9].…”
