Numerical framework for a morphology adaptive multi-field two-fuid model in OpenFOAM

Meller, R.; Schlegel, F.; Lucas, D.

A solver for multiphase flows based on the incompressible Eulerian multi-field two-fluid model for the OpenFOAM release of The OpenFOAM Foundation for numerical simulations of multiphase flows with morphology changes and resolved interfaces.


  • morphology adaptive modeling framework for modelling of dispersed and resolved interfaces based on Eulerian multi-field two-fluid model
  • compact interpolation method according to Cubero et al. (Comput Chem Eng, 2014, Vol. 62, 96-107), including virtual mass
  • numerical drag according to Strubelj and Tiselj (Int J Numer Methods Eng, 2011, Vol. 85, 575-590) to describe resolved interfaces in a volume-of-fluid like manner
  • strong phase coupling resolved by partial elimination algorithm
  • selected test cases:
    • a two-dimensional gas bubble, rising in a liquid, which is laden with micro gas bubbles, and
    • a two-dimensional stagnant stratification of water and oil, sharing a large-scale interface
