The breakup model developed by Luo and Svendsen (1993)
implemented into CFD modelling of gas-liquid two-phase
flows assumes that the bubble shapes are spherical. The
simulation results usually yield an unreliable prediction of the
break-up of very small bubbles. To the best knowledge of the
authors, incorporation of the bubble shape variation into the
break-up model has been rarely documented. The current study
intends to propose and implement an improved bubble breakup
model which accounts for variation of bubble shapes when
solving the population balance equations for CFD simulation of
gas-liquid two-phase flows in bubble columns.
