Piecewise Field-Aligned Finite Element Method for Multi-Mode Nonlinear Particle Simulations in tokamak plasmas
Zhixin Lu, Guo Meng, Eric Sonnendrücker +5
This paper presents a novel approach for simulating plasma instabilities in tokamak plasmas using the piecewise field-aligned finite element method in combination with the particle…
Gyrokinetic Electromagnetic Particle Simulations in Triangular Meshes with C1 Finite Elements
Zhixin Lu, Guo Meng, Roman Hatzky +6
The triangular mesh-based gyrokinetic scheme enables comprehensive axis-to-edge studies across the entire plasma volume. Our approach employs triangular finite elements with first-…
Indirect nonlinear interaction between toroidal Alfvén eigenmode and ion temperature gradient mode mediated by zonal structures
Qian Fang, Guangyu Wei, Ningfei Chen +3
The indirect nonlinear interactions between toroidal Alfvén eigenmode (TAE) and ion temperature gradient mode (ITG) are investigated using nonlinear gyrokinetic theory and ballooni…
Drift wave solitons and zonal flows: implication on staircase formation
Ningfei Chen, Liu Chen, Fulvio Zonca +1
The self-consistent nonlinear interaction of drift wave (DW) and zonal flow (ZF) is investigated using nonlinear gyrokinetic theory, with both spontaneous excitation and beat-drive…
Calculation of toroidal Alfvén eigenmode mode structure in general axisymmetric toroidal geometry
Guangyu Wei, Matteo Valerio Falessi, Tao Wang +2
A workflow is developed based on the ideal MHD model to investigate the linear physics of various Alfvén eigenmodes in general axisymmetric toroidal geometry, by solving the couple…
On beat-driven and spontaneous excitations of zonal flows by drift waves
Liu Chen, Zhiyong Qiu, Fulvio Zonca
Using the slab plasma as a paradigm model, we have derived analytically equations for the nonlinear generation of zero-frequency zonal flows by electron drift waves including, on t…
