Simulations
of two-phase (air and water) flow in a pipe are very relevant topics; however,
with the increased understanding of multiphase flow in pipes, the application
of computational fluid dynamics (CFD) in other complex flow geometries involved
in oil & gas industries are becoming more common. The current paper
attempts to study two-phase flow characteristics in the horizontal concentric
annulus using the CFD approach. The
model was simulated in a concentric annulus test section with an overall length
of 10.8 m and outer diameter (OD) of 0.0768 m and inner diameter (ID) of 0.060 m.
The model predicted the liquid holdup, and flow regime for the dispersed bubble
flow. The volume of fraction (VOF) multiphase model and turbulence models
(Realizable k- ε) were implemented to understand the gas and liquid holdup
scenarios for flow in the horizontal annulus.
