Nonlinear MHD simulations of external kinks in quasi-axisymmetric stellarators using an axisymmetric external rotational transform approximation
Rohan Ramasamy, Matthias Hoelzl, Erika Strumberger +2
Reduced magnetohydrodynamic (MHD) equations are used to study the nonlinear dynamics of external kinks in a quasi-axisymmetric (QA) stellarator with varying fractions of external r…
A three-dimensional reduced MHD model consistent with full MHD
Nikita Nikulsin, Matthias Hoelzl, Alessandro Zocco +2
Within the context of a viscoresistive magnetohydrodynamic (MHD) model with anisotropic heat transport and cross-field mass diffusion, we introduce novel three-term representations…
Magnetic flux pumping in 3D nonlinear magnetohydrodynamic simulations
I. Krebs, S. C. Jardin, S. Günter +4
A self-regulating magnetic flux pumping mechanism in tokamaks that maintains the core safety factor at , thus preventing sawteeth, is analyzed in nonlinear 3D magnetohy…
Double-resonant fast particle-wave interaction
Mirjam Schneller, Philipp Lauber, Michael Brüdgam +2
In future fusion devices fast particles must be well confined in order to transfer their energy to the background plasma. Magnetohydrodynamic instabilities like Toroidal Alfvén Eig…
