Slug flows are a typical intermittent two-phase flow pattern that can occur\nin submarine pipelines connecting the wells to the production facility and that\nis known to cause undesired consequences. In this context, computational fluid\ndynamics appears to be the tool of choice to understand their formation.\nHowever, few direct numerical simulations of slug flows are available in the\nliterature, especially using meshless methods which are known to be capable of\nhandling complex problems involving interfaces.\n In this work, a 2D study of the instability processes leading to the\nformation of intermittent flows in pipes is conducted using an existing\nmultiphase smoothed particle hydrodynamics formulation associated with inlet\nand outlet boundary conditions. This paper aims to demonstrate the\napplicability of smoothed particle hydrodynamics to a given set of\nclose-to-industry cases.\n First, we check the ability of our implementation to reproduce flow regimes\npredicted by Taitel and Duckler's flow map. Then, we focus on the transition\nprocesses from one flow pattern to the other. Finally, we present the results\nobtained for more realistic cases with high density and viscosity ratios.\n
