Abstract


  • The CFD modeling of two dimensional multiphase

    ows is a useful tool in industry,

    although accurate modeling itself remains a dicult task. One of the diculties is

    to track the complicated topological deformations of the interfaces between dierent

    phases. This paper describes a marker-particle method designed to track

    uid interfaces

    for

    uid

    ows of at least three phases. The interface-tracking scheme presented

    in this paper is the rst part of a series of papers presenting our complete model

    based on a one-eld Godunov marker-particle projection scheme (GMPPS). In this

    part, we shall focus on the presentation of the interface-tracking scheme and the

    kinematic tests we conducted to examine the scheme's ability to accurately track

    interfacial movements typied by vorticity-induced stretching and tearing of the interface.

    Our test results show that for a set of carefully-designed and commonly-used

    error measures, relative percentage errors never exceed two percent for all of the

    tests and grid sizes considered, provided a sucient number of marker particles are

    used. We shall also demonstrate that the method is of second order accuracy and

    the interface transition width remains constant never exceeding three cell widths.
