Abstract
Geometric distribution are assumed by different two-phase flows, named flow patterns depending on liquid and gas velocity, pressure, fluid properties, among others. The gas-liquid two-phase flow is subject of several studies due the wide frequency on industries, using as example the slug flow which has as mainly characteristic the phases that are distributed in an elongated bubble and a liquid piston. Several theoretical models have been proposed, which need additional correlations for the resolution of the model equations. One of the most used correlations are given for the bubble front velocity that has been analyzed by several authors. The objective of this work is to analyze the bubble front velocity behavior due the velocities in a horizontal pipeline of 25.8mm of internal diameter and 11m of length seeking expand knowledge in this type of flow and compare the results obtained from experiments with correlations obtained from the literature. The results indicate divergence with other correlations, mainly for low flow rates. Finally, his work can be used as a database for analysis of two-phase flow models.
