Book excerpt: The multiphase flow has always been a major concern since it is encountered in many industrial processes that are crucial. Gas/non-Newtonian two-phase flow is found in the upstream of the petroleum industry, where slug flow is the most common flow pattern. This flow pattern has complex hydrodynamics which are crucial to study and evaluate. This study assessed the two-phase gas/non-Newtonian fluid flow in different configurations of pipes. The model was developed using Computational Fluid Dynamics (CFD) with an orthogonal mesh to evaluate the behavior of the slug dynamics in the different configurations. The model Volume of Fluid (VOF) was used to estimate and predict the most important parameters: pressure drop, slug frequency and length. First the model was validated with experimental data found in literature in a horizontal 9 m long glass pipe, with an inner diameter of 22.8 mm. The validation was made with CarboxyMethyl Cellulose CMC-water solutions as test fluids...
