Slug Flow Evolution Along Horizontal Pipelines by the Two Fluid Model

At the present work a numerical analysis of the slug flow evolution along horizontal pipelines is performed, based on the Two-Fluid Model. For the statistically steady state regime, the slug characteristics, such as frequency, length and translational velocity are determined. An air and water two-phase fluid mixture is examined. The influence of the entrance liquid holdup is address. The frequency, translation velocity and length are compared with empirical correlations available in the literature with very good agreement.
