Simplified Correlation for Liquid Holdup in a Horizontal Two-Phase Gas-Liquid Annular Flow

Abstract

This paper presents the development of a simplified correlation for the prediction of liquid holdup a two-phase gas liquid annular flow in a horizontal pipe. The correlation was developed on the basis of the combination of the present experimental data and the available previous data and correlations. The proposed correlation could predict the liquid holdup with an average error 15.2%. Generally, 80% of the total data lie within ±20% error band, 97% data within ±30% error band, and 100% data within ±30% error band. All available previous data and correlation have mean absolute error (MAE)in the range of 4.5% to 27.8%.
