Characterisation of Gas-Liquid Two-Phase Slug Flows in Horizontal Pipe

Abstract: Experiments were carried out at different stratified air-water flow settings as well as different liquid 'slug' push in rates. The experimental facility, the LOTUS (Long Tube System) facility, was then situated in the Pilot Plant area of the Department of Chemical Engineering at Imperial College London. Understanding the nature of slugs and characterizing them help significantly in slug flow modelling. Some of the properties of slug determined in this work, include liquid film height, slug film height, film holdup, slug holdup, slug front velocity and the slug length. Though, the slugs were not generated due to high gas-liquid velocities, the results compared favourably with previous work and models on characteristics of slug flow.
