Pressure and temperature relaxation limit for a one-velocity Baer-Nunziato model

Cosmin Burtea, Timothée Crin-Barat, Pierre Gonin--Joubert

The dynamics of two-phase flows out of mechanical and thermal equilibrium are described by a partially dissipative first-order quasilinear system with stiff interaction terms assoc…

Vanishing conductivity limit for the 1D compressible Navier-Stokes system

Pierre Gonin--Joubert

The present article studies solutions to the compressible Navier-Stokes equations for ideal gases in one dimension when thermal conductivity is present but very weak, while viscosi…

Global in time justification of a two-phase averaged system for heat-conducting ideal gases

Pierre Gonin--Joubert

In this article, we mathematically justify (globally in time) a Baer-Nunziato type system from the non-isentropic compressible Navier-Sokes equations for heat conducting ideal gase…

On the relaxation towards mechanical equilibrium for two-pressure compressible flows

Cosmin Burtea, Timothée Crin-Barat, Pierre Gonin--Joubert

We introduce a symmetrization of a one-velocity two-pressures Baer-Nunziato type model for mixtures of barotropic compressible fluids. It allows us to justify the zero compaction v…

Two-phase averaged system justification for ideal gases without conductivity

D Bresch, C Burtea, P Gonin--Joubert +1

This article concerns the mathematical justification of an averaged system of partial differential equations governing the evolution of a two-phase mixture of compressible ideal fl…
