Predicting slug liquid holdup in a two-phase gas–liquid vertical flow

Journal of Engineering and Applied Science
The accuracy of existing liquid holdup models is limited to the range of data used in their development. In this study, a dynamic model for predicting liquid holdup in a two-phase gas liquid vertical flow is developed using artificial neural networks and
