Taylor bubble velocity for inclined pipes with stagnant liquid for an ample range of properties and inclination angles that outperforms current correlations. The Taylor bubble velocity correlation is extracted from an ample numerical database generated with 3D CFD Direct Numerical Simulations with level set as the Interface Tracking Method. Taylor bubble velocity correlation for use in slug flow mechanistic models. CFD numerical method validated with vertical and inclined pipe experiments.
