Nonlinear reversed shear Alfven eigenmode saturation due to spontaneous zonal current generation
Shizhao Wei, Tao Wang, Ningfei Chen +1
General nonlinear equations describing reversed shear Alfven eigenmode (RSAE) self-modulation via zero frequency zonal structure (ZFZS) generation are derived using nonlinear gyrok…
Soliton generation and drift wave turbulence spreading via geodesic acoustic mode excitation
Ningfei Chen, Shizhao Wei, Guangyu Wei +1
The two-field equations governing fully nonlinear dynamics of the drift wave (DW) and geodesic acoustic mode (GAM) in the toroidal geometry are derived in nonlinear gyrokinetic fra…
Effects of radial electric field on ion temperature gradient driven mode stability
Ningfei Chen, Hanyuan Hu, Xiangyu Zhang +2
The local stability of ion-temperature gradient driven mode (ITG) in the presence of a given radial electric field is investigated using gyrokinetic theory and ballooning mode form…
Nonlinear coupling of reversed shear Alfven eigenmode and toroidal Alfven eigenmode during current ramp
Shizhao Wei, Yahui Wang, Peiwan Shi +3
Two novel nonlinear mode coupling processes for reversed shear Alfven eigenmode (RSAE) nonlinear saturation are proposed and investigated. In the first process, RSAE nonlinearly co…
