The global version of the gyrokinetic turbulence code GENE
The understanding and prediction of transport due to plasma microturbulence is a key open problem in modern plasma physics, and a Grand Challenge for fusion energy research. Ab initio simulations of such small-scale, low-frequency turbulence are to be based on the gyrokinetic equations, a set of nonlinear integro-differential equations in reduced (five-dimensional) phase space. In the present p...
متن کاملEffects of geometry on linear and non-linear gyrokinetic simulations, and development of a global version of the GENE code
Using an interface with the ideal MHD equilibrium code CHEASE, numerical simulations are performed in realistic Tokamak geometry with the gyrokinetic flux tube code GENE [1, 2]. As a starting point in view of a more general study of geometrical effects on various types of microturbulence, elongation and triangularity scans are carried out in the ITG regime. In particular, the main dependence of...
متن کاملGYSELA , a full- f global gyrokinetic Semi-Lagrangian code for ITG turbulence simulations
This work addresses non-linear global gyrokinetic simulations of ion temperature gradient (ITG) driven turbulence with the GYSELA code. The particularity of GYSELA code is to use a fixed grid with a Semi-Lagrangian (SL) scheme and this for the entire distribution function. The 4D non-linear drift-kinetic version of the code already showns the interest of such a SL method which exhibits good pro...
متن کاملA 5D gyrokinetic full-f global semi-Lagrangian code for flux-driven ion turbulence simulations
This paper addresses non-linear gyrokinetic simulations of ion temperature gradient (ITG) turbulence in tokamak plasmas. The electrostatic Gysela code is one of the few international 5D gyrokinetic codes able to perform global, full-f and flux-driven simulations. Its has also the numerical originality of being based on a semi-Lagrangian (SL) method. This reference paper for the Gysela code pres...
متن کاملGlobal full-f gyrokinetic simulations of plasma turbulence
Critical physical issues can be specifically tackled with the global full-f gyrokinetic code GYSELA. Three main results are presented. First, the selfconsistent treatment of equilibrium and fluctuations highlights the competition between two compensation mechanisms for the curvature driven vertical charge separation, namely, parallel flow and polarization. The impact of the latter on the turbul...
