Pressureless Euler-Poisson Equations -- CFD Online Discussion Forums

April 12, 2001, 21:18	Pressureless Euler-Poisson Equations	#1
Mikael Tushensson Guest Posts: n/a	Hi, CFD People! I'm solving 1D pressureless Euler-Poisson equations for the cold electron plasma, i.e. continuity equation, pressureless Euler equation with electrostatic force and Poisson equation for electrons and immobile ions. Can you recommend me a numerical method for the treating the problem? Also I have some more specific questions: Question 1. Is it possible to implement the Riemann solver in the case of pressureless equations and, if yes, how ? Question 2. Should I use the splitting procedure for the separate treating of homogeneous part of hydrodynamical equations and inhomogeneous part with Poisson equation?
