A drift-kinetic Semi-Lagrangian 4D code for ion turbulence simulation
A new code is presented here, named Gyrokinetic SEmi-LAgragian (GYSELA) code, which solves 4D drift-kinetic equations for ion temperature gradient driven turbulence in a cylinder (r,h,z). The code validation is performed with the slab ITG mode that only depends on the parallel velocity. This code uses a semi-Lagrangian numerical scheme, which exhibits good properties of energy conservation in n...
متن کاملA semi-Lagrangian code for nonlinear global simulations of electrostatic drift-kinetic ITG modes
A semi-Lagrangian code for the solution of the electrostatic drift-kinetic equations in straight cylinder configuration is presented. The code, CYGNE, is part of a project with the long term aim of studying microturbulence in fusion devices. The code has been constructed in such a way as to preserve a good control of the constants of motion, possessed by the drift-kinetic equations, until the n...
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 کاملComputing ITG turbulence with a full-f semi-lagrangian code
This paper 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 SemiLagrangian (SL) scheme and this for the full distribution function. The 4D non-linear driftkinetic version of the code already showns the interest of such a SL method which exhibits good properties of energy con...
متن کاملLagrangian dynamics of drift-wave turbulence
The statistical properties of Lagrangian particle transport are investigated in dissipative drift-wave turbulence modelled by the Hasegawa–Wakatani system. By varying the adiabaticity parameter c, the flow regime can be modified from a hydrodynamic limit for c = 0 to a geostrophic limit for c → ∞. For c of order unity the quasi-adiabatic regime is obtained, which might be relevant to describe t...
