Qualitative properties of the solutions to the Navier-Stokes equations for compressible fluids
Quasineutral limit of the Euler-Poisson system for ions in a domain with boundaries II
In this paper, we study the quasineutral limit of the isothermal Euler-Poisson equation for ions, in a domain with boundary. This is a follow-up to our previous work [5], devoted to no-penetration as well as subsonic outflow boundary conditions. We focus here on the case of supersonic outflow velocities. The structure of the boundary layers and the stabilization mechanism are different.
