Quasi-Neutral Multi-Fluid Models: A Variational Principle and Numerical Methods — •Sayyed Amin Raiessi Toussi, Omar Maj, and Tomasz Tyranowski — Max Planck Institute for Plasma Physics, D-85748 Garching, Germany

Quasi-neutral multi-fluid models are commonly used to describe particle and energy transport in the edge and scrape-off layer (SOL) of magnetically confined fusion plasmas [R. Schneider, Contrib. Plasma Phys., 46, 2006]. In this work we present a generalization of the variational principle for incompressible Euler equations [V. Arnold, Ann. Inst. Fourier 16, 319-361 (1966)] to quasi-neutral multi-fluid models, including only ideal processes. Also some preliminary considerations on appropriate numerical methods are offered.
