Liquid entrainment in annular two-phase flow in vertical pipes

Abstract EN

In the present work, a semi-mechanistic model to predict the liquid entrainment in annular two-phase flow in vertical pipe.

This model is originally a modified version to the model of Martin et.

Al.

(2006).

The experimental tests have conducted by the literature for air-water system flowing through vertical pipe of 9.5 mm in diameter [Ryan 2004].

The comparison achieved by calculating the average and absolute percent error between the measured entrainment and the predicted entrainment by eight methods available in the literature.

The comparison showed the best results of the present model among the others.
