Numerical investigation of models for drag, lift, wall lubrication and turbulent dispersion forces for the simulation of gas–liquid two-phase flow
S Yamoah, R Martínez-Cuenca, G Monrós… - … Research and Design, 2015 - Elsevier
In order to qualify CFD codes for accurate numerical predictions of transient evolution of flow
regimes in a vertical gas–liquid two-phase flow in a pipe, suitable closure models (inter-
phase forces) for the momentum exchange between the continuous and dispersed phases
are needed. In this study, under the assumption of monodisperse bubbles, a consistent set
of inter-phase force models have been investigated. The effect of Drag Force, Lift Force, Wall
Lubrication Force and Turbulent Dispersion Force has been assessed. The predicted local …
