A four-field three-phase flow model with both miscible and immiscible components
TL;DR: In this article, a three-phase flow model with hybrid miscibility constraints is proposed, where three immiscible phases are considered (liquid water, liquid metal and gas) but the gaseous phase is composed with two miscible components (steam water and non-condensable gas).

Development of an algebraic fractional step scheme for the primitive formulation of the compressible Navier-Stokes equations
TL;DR: In this article, a finite-element solver based on a fractional step scheme was proposed to uncouple the calculation of the Navier-Stokes equations providing important savings in computational cost.

Numerical Modelling of the Rapid Depressurisation and Outflow of High Pressure Containments in the Framework of Carbon Capture and Sequestration
TL;DR: In this article, the authors present the development, testing and validation of various transient flow models taking account of the above phenomena, including a Homogeneous equilibrium mixture (HEM) pipe flow model, a homogeneous relaxation mixture (HRM), a two-fluid mixture (TFM), and an integral jet expansion model, where the conservation equations are solved separately for each constituent fluid phases during decompression.

Application of a Two-Fluid Model to Simulate the Heating of Two-Phase Flows
TL;DR: In this article, the simulation of two-phase flows on the basis of a two-fluid model that allows to account for the disequilibrium of velocities, pressures, temperatures and chemical potentials (mass transfer) is performed using a fractional step method treating separately the convective part of the model and the source terms.

TL;DR: In this paper, the authors proposed a method of characteristics used for numerical computation of solutions of fluid dynamical equations is characterized by a large degree of non standardness and therefore is not suitable for automatic computation on electronic computing machines, especially for problems with a large number of shock waves and contact discontinuities.

TL;DR: In this article, two-phase field equations based on time average are proposed. But they do not consider the effect of structural materials in a control volume on the two-fluid model.

A two-phase mixture theory for the deflagration-to-detonation transition (ddt) in reactive granular materials
Melvin R. Baer,J.W. Nunziato +1 more
TL;DR: In this article, a two-phase mixture theory is presented which describes the deflagration-to-detonation transition (DDT) in reactive granular materials, based on the continuum theory of mixtures formulated to include the compressibility of all phases and the compaction behavior of the granular material.
