Wall Ion Loss Reduction by Acceleration Zone Shifting in Anode-Layer Hall Thruster
Rei Kawashima, Yushi Hamada, Shu Kawabata +2
In this study, wall ion loss and erosion rate are evaluated in the RAIJIN thruster. The novelty of this work is the detailed analysis of measured guard-ring (metallic channel wall)…
Two-dimensional hybrid model of gradient drift instability and enhanced electron transport in a Hall thruster
Rei Kawashima, Kimiya Komurasaki
An axial-azimuthal two-dimensional Hall thruster discharge model was developed for analyzing gradient drift instability (GDI) and cross-field electron transport enhancement induced…
High-order upwind and non-oscillatory approach for steady state diffusion, advection-diffusion and application to magnetized electrons
Amareshwara Sainadh Chamarthi, Kimiya Komurasaki, Rei Kawashima
Steady state simulations} of magnetized electron fluid equations with strong anisotropic diffusion based on the first-order hyperbolic approach is carried out using cell-centered h…
Two-dimensional Modeling of the Hall Thruster Discharge with Non-uniform Propellant Supply in Azimuth
Rei Kawashima, Junhwi Bak, Kimiya Komurasaki +1
A two-dimensional simulation is conducted to investigate the effect of cross-field electron transport enhancement in the Hall thruster discharge caused by the nonuniform propellant…
A flux-splitting method for hyperbolic-equation system of magnetized electron fluids in quasi-neutral plasmas
R. Kawashima, K. Komurasaki, T. Schoenherr
A flux-splitting method is proposed for the hyperbolic-equation system (HES) of magnetized electron fluids in quasi-neutral plasmas. The numerical fluxes are split into four catego…
A hyperbolic-equation system approach for magnetized electron fluids in quasi-neutral plasmas
R. Kawashima, K. Komurasaki, T. Schoenherr
A new approach using a hyperbolic-equation system (HES) is proposed to solve for the electron fluids in quasi-neutral plasmas. The HES approach avoids treatments of cross-diffusion…
