Abstract
ABSTRACTA predictive two-phase CFD model requiring no experimental input is used to estimate dispersed phase holdup in a pulsed sieve plate column (PSPC). Drop diameter used in simulations is obtained from a reported correlation. Reported experimental data are used for validation. Average error in estimated values of dispersed phase holdup is about 17% when standard Kumar–Hartland drag model is used. The average error is reduced to about 6% by modifying the drag model. Efficacy of the CFD model embedding the modified drag model is tested with the reported experimental data of PSPCs having different geometries, operated with different phase systems.
