Long-time dynamics of partially dissipative hyperbolic systems with non-autonomous coefficients

Timothée Crin-Barat, Ling-Yun Shou, Qimeng Zhu

We study quasilinear symmetrizable partially dissipative hyperbolic systems with non-autonomous relaxation coefficients in (). The existence of global strong…

On the decay estimates of a nonlocal convection-diffusion Hamer system

Timothée Crin-Barat, Belkacem Said-Houari

We consider the multi-dimensional Hamer model for radiating gases in its coupled hyperbolic--elliptic formulation. By means of energy estimates, we establish the global well-posedn…

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…

The compressible Euler system with damping in hybrid Besov spaces: global well-posedness and relaxation limit

Timothée Crin-Barat, Zihao Song

We investigate the global well-posedness of the compressible Euler system with damping in Rd (d\geq1) and its relaxation limit toward the porous medium equation. In [12], the first…

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…

Compressible Euler equations with time-dependent damping in the critical regularity setting: global well-posedness and strong relaxation limit

Timothée Crin-Barat, Xinghong Pan, Ling-Yun Shou +1

We investigate the relaxation problem and the diffusion phenomenon for the compressible Euler system with a time-dependent damping coefficient of the form in $\m…
