An Euler-Euler two-fluid CFD model is developed to capture liquid–liquid two-phase hydrodynamics in an air pulsed column having a novel internal. A new plate type internal namely circular slotted plates is reported. The plates feature concentric rings (3 mm wide) of different diameters as openings/free areas available for counter-current two-phase flow. A 2D axisymmetric model is developed. The model solves conservation equations for mass and momentum for each phase and that of turbulence variables for the mixture. Monodispersed drops have been assumed. The CFD model is used to estimate dispersed phase holdup in the column. Air pulsed column of diameter 3 inch is used in the study. The percentage opening area of the plate is 20%. Five plates, 0.05 m apart, have been used to keep computation time within reasonable limits. Water and 30% (V/V) TBP in dodecane are considered as continuous phase and dispersed phase respectively. Unstructured triangular mesh with mesh density of 1.15 × 106 elements/m2 has been used. Standard k-ε turbulence model (mixture) has been used to estimate the turbulence parameters. Drag coefficient is estimated using Schiller-Naumann drag model. The model has been validated with the experimental data on dispersed phase holdup reported in literature. Dispersed phase holdup is seen to increase with increase in pulsing velocity. A comparison of dispersed phase holdup for the slotted internal vis-à-vis disc and doughnut internal is also reported.
