Two-fluid effects on the nonlinear dynamics of RFP relaxation
Wentan Yan, Ping Zhu, Hong Li +2
This study investigates the role of two-fluid effects during magnetic relaxation in reversed-field pinch (RFP) plasmas. Within the multiple-helicity (MH) regime, two-fluid simulati…
Effects of external magnetic field ripple on FRC equilibrium
Zitong Qu, Ping Zhu, Zhipeng Chen +1
The two-dimensional equilibrium of Field-Reversed Configuration (FRC) plasma in presence of an external ripple magnetic field is computed to show the emergence of multiple magnetic…
Enhanced dynamo drive for the sawtooth relaxation process due to non-uniform resistivity distribution in a reversed field pinch
Wentan Yan, Ping Zhu, Hong Li +3
In this work, we use the three-dimensional resistive MHD code NIMROD to investigate the impact of resistivity inhomogeneity on the sawtooth process of an reversed field pinch (RFP)…
Formation of quasi-single helicity state from a paramagnetic pinch in KTX regime
Bing Luo, Ping Zhu, Wentan Yan +2
The formation of quasi-single helicity (QSH) state from a paramagnetic pinch in the KTX-RFP regime has been observed in recent NIMROD simulations. The quasi-single helicity state h…
