A survey is given of continuum theories that have been developed to model mixtures of
immiscible constituents, such as bubbly liquids, fluid-particle mixtures, fluid saturated porous …

This report describes the MFIX (Multiphase Flow with Interphase exchanges) computer
model. MFIX is a general-purpose hydrodynamic model that describes chemical reactions …

A multiphase particle-in-cell (MP-PIC) method has been developed. This numerical
technique draws upon the best of Eulerian/Eulerian continuum models and …

Here, recent developments in the key numerical approaches to water hammer modelling are
summarized and critiqued. This paper summarizes one-dimensional modelling using the …

This paper presents a new, generalized two‐phase debris flow model that includes many
essential physical phenomena. The model employs the Mohr‐Coulomb plasticity for the …

A general classification of two-phase flows and a number of possible ways to formulate two-
fluid models are discussed. The two-fluid model is adopted, and a general procedure to …

Flow regimes of dense‐phase vertical pneumatic transport of solids, referred to in the
literature as circulating fluidized beds, have been computed using a generalization of the …

Equations for two-phase flow are developed where the interfacial pressure pi is the closure
variable. The assumption that pi is constant leads to variations of the single pressure model …

Erosion in bubbling fluidized‐bed combustors is a serious issue that may affect their
reliability and economics. Available evidence suggests that the key to understanding this …

For some time it has been known that many of the two-phase flow models lead to ill-posed
Cauchy problems because they have complex characteristic values. A necessary condition …
