Abstract
In liquid-gas two-phase flow, the phases can be distributed in different configurations according to the flow characteristics, namely: fluid flow rates, properties of each phase and pipeline geometry. Those different configurations are known as flow patterns. Slug flow is one of those patterns and is easily found in oil and gas production lines. This flow pattern is characterized by a unit cell comprising an aerated liquid slug and an elongated bubble surrounded by a liquid film. Slug flow can be properly characterized by the mathematical modeling of the elongated bubble shape whose numerical solution yields liquid and gas fractions, elongated bubble and liquid slug lengths. This study presents a literature review of theoretical models for determining the elongated bubble shape. Moreover, it analyzes experimental results for determining the influence of characteristic parameters of the two-phase slug flow on the elongated bubble shape.
