Abstract Two axisymmetric dimensional Eulerian/Eulerian simulation of two-phase
(gas/liquid) transient flow was performed for both stationary and rotating columns under zero
gravity. Multiphase flow simulation is modelled using flow algorithm based on the finite-
volume method to simulate bubble population balance modelling. Two coalescence kernels,
one for laminar flow and the other for laminar shear flow, are experimented under zero
gravity using special user defined functions. Effects of rotation speed are investigated at …
