Numerical simulation of the effect of plasma ion viscosity on the heating and compression in dynamic Z -pinch implosions

Feifei Li, Xuming Feng, Guozhuang Li, Zhao Wang et autres

Abstract This study uses a one-dimensional two-temperature magnetohydrodynamic model to simulate the Z -pinch process in deuterium plasma. The onset time of viscous effects is determined using the Reynolds number. The energy evolution and temperature profile during the implosion process, with and …

Magnetic Field Effects on Energy Coupling in Scaled Laser-Driven Magnetized Liner Inertial Fusion

Xuming Feng, Guozhuang Li, Hua Zhang, Shijia Chen et autres

In scaled laser-driven magnetized liner inertial fusion (MagLIF), externally applied magnetic fields improve energy coupling by suppressing electron thermal conduction, enhancing Joule heating, and increasing α-particle energy deposition. However, confinement can be significantly degraded by magnetic flux transport, dominated by resistive diffusion, …

Collisions of proton or highly charged ion–atom in a strong magnetic field and dense quantum plasmas

Guozhuang Li, Sheng Zhang, Zhi-Hong Jiao, Qiang Yan et autres

Magneto inertial fusion driven by heavy ions beam (HIB) is a very attractive potential approach for the nuclear energy system. One of the key issues is to investigate the interaction process of the HIB-target considering the condition of plasma screening and strong …

Charge transfer in collisions of H+, Li3+, Be4+ and O7+ ions with He atom based on 4-classical trajectory Monte Carlo method

Guozhuang Li, Sheng Zhang, Zhi-Hong Jiao, Xinxia Li

The classical trajectory Monte Carlo (CTMC) method is a common method to study the charge-transfer and impact-ionization cross sections for the collisions between ions and atoms, and the heavy particle collision in astrophysics and laboratory plasma environment. Here in this work, we …
