Comparative assessment and possible applications of three models of Taylor slug flows

•Extensive comparison of three modeling approaches for Taylor slug flows and their corresponding modeling output.•Investigation of the different flow regimes of a coflow arrangement accompanied by a sensitivity study on droplet characteristics.•Modeling guidelines for liquid-liquid and liquid-gas simulations at low capillary numbers. [Display omitted] In this work, a versatile modeling platform, employing computational fluid dynamics (CFD) techniques to simulate liquid-liquid and liquid-gas Taylor slug flow, is presented. This platform consists of three two-dimensional, axisymmetric models, whose output can be used in various applications for which examples are provided. Modeling guidelines to decrease the simulation time and to mitigate numerical artifacts occurring at low values of the Capillary number, called spurious currents, are discussed. Moreover, to test capabilities outside the Taylor slug flow regime, other flow regimes occurring in a coflow arrangement were investigated and a sensitivity analysis on the resulting droplet characteristics was performed.
