In this talk, the combined quasi-neutral and zero-viscosity limits of the two-fluid Navier-Stokes-Poisson systems (one for ion and another for electron) with boundary are rigorously proved by investigating the existence and the stability of the boundary layers. The non-penetration boundary condition for velocities and Dirichlet boundary condition for electric potential are considered. Based on conormal energy estimate, we showed that the solutions for the system then converge towards the solutions of the one-fluid compressible Euler system.
