Approximate solutions of the baer-nunziato model
Fabien Crouzet,Frédéric Daude,Pascal Galon,Philippe Helluy,Jean-Marc Hérard,Olivier Hurisse,Yujie Liu +6 more
TL;DR: In this article, the accuracy of approximations of the Baer-Nunziato two-phase flow model is examined, and two distinct numerical schemes are investigated, including a classical second-order extension relying on symmetrizing variables.

Computing Two-Fluid Models of Compressible Water-Vapour Flows with Mass Transfer
TL;DR: This paper is devoted to the simulation of water-vapour flows with mass transfer, using the two-fluid approach proposed in 8, 11, 12,17,22,23,27, and some attempts to deal with pressure-velocity-temperature relaxation effects have been recently reported.

A pressure-based method for weakly compressible two-phase flows under a Baer-Nunziato type model with generic equations of state and pressure and velocity disequilibrium.
Barbara Re,Rémi Abgrall +1 more
TL;DR: In this article, a pressure-based Baer-Nunziato type model is proposed for weakly compressible multiphase flows, which includes relaxation terms characterized by user-defined finite parameters to drive the pressure and velocity of each phase toward the equilibrium.

Computation of fast depressurization of water using a two-fluid model: revisiting Bilicki modelling of mass transfer
TL;DR: In this paper, a simple but physically-based modeling of the mass transfer for the depressurization of water is proposed, which relies on the work of Bilicki & Kestin in the homogeneous frame.

Finite difference methods for numerical computation of discontinous solutions of the equations of fluid dynamics
Finite difference method for numerical computation of discontinuous solutions of the equations of fluid dynamics
S. K. Godunov,I. Bohachevsky +1 more
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.
