000013979 520__ $$2eng$$aIn the mechanistic modeling of slug flow, the Taylor bubble velocity has been determined to strongly affect the predictions of liquid holdup (or void fraction) and pressure gradient. The objective of this work is to improve these predictions through a better Taylor bubble velocity closure relation. Computational Fluid Dynamics (CFD) with Level-Set as the Interface Tracking Method (ITM) are employed to generate a large numerical database of Taylor bubbles in stagnant, upward and downward flow for an ample range of fluid properties and pipe geometries (M o ∈ [1 · 10−6 , 5 · 103 ], Eo ∈ [10, 700], θ ∈ [−90◦ , 90◦ ], Re ∈ [0, 1000]). The new correlation, obtained using this database, has been applied to those mechanistic models observing higher improvements as the inclination with respect to the horizontal decreases.
