TLDR
A survey of theories of immiscible mixtures can be found in this article, where it is emphasized that the immiscibility of such mixtures has important consequences concerning the forms of the constitutive equations, and that it can also result in the mixtures exhibiting microstructural effects.About:

ReportDOI
MFIX documentation theory guide
TL;DR: This report describes the MFIX (Multiphase Flow with Interphase exchanges) computer model, a general-purpose hydrodynamic model that describes chemical reactions and heat transfer in dense or dilute fluid-solids flows, flows typically occurring in energy conversion and chemical processing reactors.
Journal ArticleDOI
Quasi–incompressible Cahn–Hilliard fluids and topological transitions
John Lowengrub,Lev Truskinovsky +1 more
TL;DR: In this article, a physically motivated regularization of the Euler equations is proposed to allow topological transitions to occur smoothly, where the sharp interface is replaced by a narrow transition layer across which the fluids may mix.
Journal ArticleDOI
Mechanics and thermodynamics of multiphase flow in porous media including interphase boundaries
TL;DR: In this paper, a macroscopic thermodynamic theory was developed to describe two-phase flow in porous media, where the authors developed a constitutive theory resulting in balance equations and thermodynamics appropriate for modelling multiphase flow.
Journal ArticleDOI
A two-fluid model for avalanche and debris flows
E. Bruce Pitman,Long Le +1 more
TL;DR: A depth-averaged ‘thin layer’ model of geophysical mass flows containing a mixture of solid material and fluid is described, derived from a ‘ two-phase’ or ‘two-fluid’ system of equations commonly used in engineering research.
Journal ArticleDOI
Heterogeneous medium. Is an equivalent macroscopic description possible
TL;DR: In this article, it is shown that the homogenization process using double scale asymptotic developments appears to be the appropriate method giving the right answer to the question, which is emphasized in two simple examples.

A theory of transversely isotropic fluids
S. J. Allen,C. N. DeSilva +1 more
TL;DR: In this article, a theory for the mechanical behavior of a fluid with a rigid microstructure is proposed, which is described by a director frame of three vectors and a second-order tensor W and its gradient are proposed as measures of the kinematics of this frame.

A mixture theory for elastic laminated composites
Hugh D. McNiven,Yalcin Mengi +1 more
TL;DR: In this paper, a theory for the dynamic response of a homogeneous, elastic, dispersive material is developed, which is derived from a general theory for all two phase periodic materials which was developed earlier.
