Comparison of Vlasov solvers for spacecraft charging simulation

Nicolas Vauchelet;  Jean-Paul Dudon;  Christophe Besse;  Thierry Goudon — 2010

ESAIM: Mathematical Modelling and Numerical Analysis

The modelling and the numerical resolution of the electrical charging of a spacecraft in interaction with the Earth magnetosphere is considered. It involves the Vlasov-Poisson system, endowed with non standard boundary conditions. We discuss the pros and cons of several numerical methods for solving this system, using as benchmark a simple 1D model which exhibits the main difficulties of the original models.

Numerical approximation of Knudsen layer for the Euler-Poisson system

Fréderique Charles;  Nicolas Vauchelet;  Christophe Besse;  Thierry Goudon;  Ingrid Lacroix–Violet;  Jean-Paul Dudon;  Laurent Navoret — 2011

ESAIM: Proceedings

In this work, we consider the computation of the boundary conditions for the linearized Euler–Poisson derived from the BGK kinetic model in the small mean free path regime. Boundary layers are generated from the fact that the incoming kinetic flux might be far from the thermodynamical equilibrium. In [2], the authors propose a method to compute numerically the boundary conditions in the hydrodynamic limit relying on an analysis of the boundary layers....
