Journal ArticleDOI
A drift-kinetic semi-Lagrangian 4D code for ion turbulence simulation
Virginie Grandgirard,Maura Brunetti,Pierre Bertrand,Nicolas Besse,Xavier Garbet,Philippe Ghendrih,Giovanni Manfredi,Yanick Sarazin,Olivier Sauter,Eric Sonnendrücker,Jan Vaclavik,Laurent Villard +11 more
TL;DR: The Gyrokinetic SEmi-LAgragian (GYSELA) code, which solves 4D drift-kinetic equations for ion temperature gradient driven turbulence in a cylinder, is found to be stable over long simulation times, including for cases with a high resolution mesh.
Journal ArticleDOI
Stellar diffusion in barred spiral galaxies
TL;DR: In this article, the radial diffusion of stars in the plane of a typical barred disk galaxy was characterized empirically by calculating the local spatial diffusion coefficient and diffusion time-scale for bulge-disk-halo N-body self-consistent systems which initially differ in the SafronovToomre-QT parameter.
Journal ArticleDOI
Full radius linear and nonlinear gyrokinetic simulations for tokamaks and stellarators: zonal flows, applied E × B flows, trapped electrons and finite beta
Laurent Villard,S.J. Allfrey,Alberto Bottino,Maura Brunetti,G. L. Falchetto,Virginie Grandgirard,Roman Hatzky,J. Nührenberg,A. G. Peeters,Olivier Sauter,S. Sorge,J. Vaclavik +11 more
TL;DR: In this article, the nonlinear development and saturation of ion temperature gradient (ITG) modes and the role of E × B zonal flows are studied with a global nonlinear δf formulation that retains parallel nonlinearity and thus allows for a check of the energy conservation property as a means of verifying the quality of the numerical simulation.
Journal ArticleDOI
Asymptotic evolution of nonlinear Landau damping
TL;DR: In this paper, the long-time evolution of nonlinear Landau damping in collisionless plasmas is analyzed by solving the Vlasov-Poisson system numerically, and the value of the parameter marking the transition between Landau's and O'Neil's regimes is determined and compared with analytical results.
Journal ArticleDOI
Nonlinear fast growth of water waves under wind forcing
TL;DR: In this article, a coordinate transformation is defined to map the forced nonlinear Schrodinger (NLS) equation into the standard NLS with constant coefficients, that has a number of known analytical soliton solutions.
