An arbitrary Lagrangian Eulerian method for three-phase flows with triple junction points

摘要: We present a moving mesh method suitable for solving two-dimensional and axisymmetric three-liquid flows with triple junction points. This employs body-fitted unstructured where the interfaces between liquids are lines of system, points (if exist) nodes. To enhance accuracy efficiency method, is constantly adapted to evolution by refining coarsening locally; dynamic boundary conditions on interfaces, in particular points, therefore incorporated naturally accurately finite-element formulation. In order allow pressure discontinuity across double-values necessary interface nodes triple-values The resulting non-linear system mass momentum conservation then solved an Uzawa zero resultant condition reinforced at each time step. used investigate rising liquid drop attached bubble lighter liquid.
