Conservative Charge and Current Deposition on Nonuniform 3D Cylindrical PIC Meshes with Residual Self-Field Diagnostics
Zhe Liu, Zhijun Zhou, Yinjian Zhao
Particle-in-cell simulations on nonuniform cylindrical meshes require deposition schemes that respect cylindrical metrics while controlling numerical self-fields. This work develop…
A Fully Electromagnetic Hybrid PIC-Fluid Model for Predictive Fusion Neutron Yield in Dense Plasma Focus
Yinjian Zhao, Zhe Liu, Qiang Sun +2
While magnetic confinement fusion (MCF) and inertial confinement fusion (ICF) remain the primary routes toward controlled fusion, progress is still constrained by energy loss, plas…
Near-Wall Pathways of Anomalous Electron Transport in Hall Thrusters Revealed by 3D PIC Simulations
Zhe Liu, Zhongping Zhao, Yinjian Zhao
Cross-field electron transport in Hall thrusters is widely attributed to high-frequency instabilities, yet its net spatial pathway remains poorly resolved. Here we perf…
Electrospray Thruster Plume Dynamics: Insights from Precise PP Coulomb Field Simulation
Zhe Liu, Yinjian Zhao
Electrospray thrusters are one important type of micropropulsion systems being developed for next-generation space missions, yet the primary challenge to their operational lifespan…
