Quasi-neutral limit for the Euler–Poisson system in the presence of plasma sheaths with spherical symmetry

Mathematical Models and Methods in Applied Sciences, 2016
The purpose of this paper is to mathematically investigate the formation of a plasma sheath near the surface of a ball-shaped material immersed in a bulk plasma, and to obtain qualitative information of such a plasma sheath layer. Specifically, we study existence and the quasi-neutral limit behavior of the stationary spherical symmetric solutions for ...

Asymptotic preserving schemes in the quasi-neutral limit for the drift-diffusion system

2011
We are interested in the drift-diffusion system near quasi-neutrality. For this system, classical explicit schemes are decoupled but subject to severe numerical constraints in the quasi-neutral regime. By constrast, the implicit discretizations are unconditionally stable but non linearly coupled.

Quasi-neutral limit of the Navier–Stokes–Fourier–Poisson system for ionic dynamics

Applicable Analysis, 2017
AbstractIn this paper, we consider the quasi-neutral limit of the compressible Navier–Stokes–Fourier–Poisson system in a periodic domain with the well-prepared initial data. We prove that the weak solution of the compressible Navier–Stokes–Fourier–Possion system converges to the strong solution of the compressible Navier–Stokes–Fourier system as long ...

Weak–strong uniqueness and quasi-neutral limit for Euler–Poisson equations

Journal of Mathematical Physics
In this paper, we investigate the weak–strong uniqueness and quasi-neutral limit of 3D modified Euler–Poisson equations. Focusing on a weak solution called the dissipative measure-valued solution as the object of study, the global existence is established based on an energy admissibility criterion and by means of relative energy method it is shown that

Boundary layers and quasi-neutral limit in steady state Euler–Poisson equations for potential flows

Nonlinearity, 2004
Summary: We study the quasi-neutral limit in the steady state Euler-Poisson system for potential flows. Boundary layers occur when the boundary conditions are not in equilibrium. We perform a formal asymptotic expansion of solutions and derive the boundary layer equations. Under the subsonic condition on the boundary and the smallness assumption on the
