A hyperbolic finite difference scheme for anisotropic diffusion equations: preserving the discrete maximum principle
Tokuhiro Eto, Rei Kawashima
A hyperbolic system approach is proposed for robust computation of anisotropic diffusion equations that appear in quasineutral plasmas. Though the approach exhibits merits of high…

Sheath Analysis of Conducting Channel Walls in Anode-Layer Hall Thruster with Acceleration Zone Shifted Downstream
Rei Kawashima
Channel wall sheath thickness in an anode-layer Hall thruster RAIJIN66 was investigated by a two-dimensional hybrid simulation and a one-dimensional sheath model. A hybrid particle…
