Numerical simulation of a compressible two-layer model: A first attempt with an implicit–explicit splitting scheme
TL;DR: This work is devoted to the numerical simulation of the compressible two-layer model developed in [16], an hyperbolic two-fluid two-pressure model dedicated to gas-liquid flows in pipes, especially stratified air-water flows.

Various choices of source terms for a class of two-fluid two-velocity models
TL;DR: In this article, the authors propose different non-classical forms for the source terms of the Baer-Nunziato model, which are more linear with respect to the conservative variables.

Simulation and preliminary validation of a three-phase flow model with energy
Hamza Boukili,Jean-Marc Hérard +1 more
TL;DR: The fractional step method proposed herein complies with the continuous entropy inequality, and implicit schemes that are considered to account for relaxation terms take their roots on the true relaxation process.

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.

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.
