A mathematical model to predict the liquid holdup in vertical slug two-phase flow in pipes

الملخص EN

In the present work, a model to predict the liquid holdup in slug, two-phase gas-liquid, upwardly flow has been developed.

This model has compared with nine published methods by using experimental tests for two types of flow systems available in the literature.

The comparison achieved using the relative performance factor (FPR) which is representing an equivalent result of the most statistical tools as: error, average error and standard deviation.

The results showed the best performance of the present model than the others for each system of flow separately.
