Abstract
In the petroleum industry, the production and transportation of oil and gas is a classic example of a multiphase flows’ occurrence. In turn, the gas-liquid flows do generally classified into three primary patterns: dispersed, separated, and intermittent. The latter consists of a unit cell which does divide into two regions that alternate along the pipe: an aerated liquid piston (slug region) and an elongated gas bubble in parallel with a thin liquid film (bubble region). The slug region aeration process is quite complex, difficulting its modeling. However, it is possible to estimate the slug liquid holdup from several correlations available in the literature. Thus, this study aims to present a comparative analysis of some of these correlations used to predict the slug liquid holdup. The correlations analyzed are calculated and compared against experimental data also available in the literature to check their limitations and accuracy. The results obtained in this study should demonstrate which correlations present more satisfactory results, although they are limited to the experimental data used for the realized comparison.
