The effect of air velocity on slugs in a confined channel

The present work focuses on the study of slugs occurring in a two-phase flow confined rectangular channel: conditions appearance and effect behavior. Three-dimensional numerical simulations have been carried out to examine superficial air velocity Volume Of Fluid model (VOF) is used track air-water interface. Validation obtained by comparing results simulated axial with experimental data determined using Laser Doppler Anemometry (LDA) technique. revealed that for fixed water level velocity, higher velocities generate slug causes channel blockage. position these timing their occurrence were correlated terms Reynolds numbers.
