  text: Phase-field methods have long been used to model the flow of immiscible fluids.
    Their ability to naturally capture interface topological changes is widely recognized,
    but their accuracy in simulating flows of real fluids in practical geometries
    is not established. We here quantitatively investigate the convergence of the
    phase-field method to the sharp-interface limit with simulations of two-phase
    pipe flow. We focus on core-annular flows, in which a highly viscous fluid is
    lubricated by a less viscous fluid, and validate our simulations with an analytic
    laminar solution, a formal linear stability analysis and also in the fully nonlinear
    regime. We demonstrate the ability of the phase-field method to accurately deal
    with non-rectangular geometry, strong advection, unsteady fluctuations and large
    viscosity contrast. We argue that phase-field methods are very promising for quantitatively
    studying moderately turbulent flows, especially at high concentrations of the
    disperse phase.
