  <dc:description>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
