Coexistence of weak and strong wave turbulence in incompressible Hall magnetohydrodynamics
Romain Meyrand, Khurom H. Kiyani, Ozgur D. Gurcan +1
We report a numerical investigation of three dimensional, incompressible, Hall magnetohydrodynamic turbulence with a relatively strong mean magnetic field. Using helicity decomposi…
A nested polyhedra model of isotropic MHD turbulence
Ö. D. Gürcan
A nested polyhedra model has been developed for magnetohydrodynamic (MHD) turbulence. Driving only the velocity field at large scales with random, divergence free forcing results i…
Generalized curvature modified plasma dispersion functions and Dupree renormalization of toroidal ITG
Ö. Gültekin, Ö. D. Gürcan
A new generalization of curvature modified plasma dispersion functions is introduced in order to express Dupree renormalized dispersion relations used in quasi-linear theory. For i…
Saturation of energetic-particle-driven geodesic acoustic modes due to wave-particle nonlinearity
A. Biancalani, I. Chavdarovski, Z. Qiu +6
The nonlinear dynamics of energetic-particle (EP) driven geodesic acoustic modes (EGAM) is investigated here. A numerical analysis with the global gyrokinetic particle-in-cell code…
Stable and unstable roots of ion temperature gradient driven mode using curvature modified plasma dispersion functions
Özgür Gültekin, Özgür D. Gürcan
Basic, local kinetic theory of ion temperature gradient driven (ITG) mode, with adiabatic electrons is reconsidered. Standard unstable, purely oscillating as well as damped solutio…
Tractable flux-driven temperature, density, and rotation profile evolution with the quasilinear gyrokinetic transport model QuaLiKiz
J Citrin, C Bourdelle, F J Casson +14
Quasilinear turbulent transport models are a successful tool for prediction of core tokamak plasma profiles in many regimes. Their success hinges on the reproduction of local nonli…
