Slug Flow Visualisation Studies

Abstract: Slug flow visualization studies are described and presented. The experimental facility called the Low Pressure (LOWPRESS) rig was domiciled at Imperial College London. This study is aimed at a visual investigation of the nature of slugs as it move a long pipeline with respect to their aeration. Flows were studied for three situations, in a horizontal pipe with stratified flow ahead of the slugs, in 1 inclined pipe with downward stratified flows towards the slugs, and in a horizontal pipe with stationary liquid film, These three experiments will reveal how slug front is entrained with gas as it moves along a pipeline.
