The role of different nonlinearities and potential vorticity conservation in two-dimensional fluid ITG models
Giridharan Paramasivam, Özgür D. Gürcan
The nature of turbulent energy cascade of simple two-dimensional fluid models of ion temperature gradient driven turbulence is studied in detail. Notably, it is observed that a min…
On Phase Transition of ITG Turbulence in the Dimits shift
L. N. Marquant, P. Morel, Ö. D. Gürcan
The transition between turbulent and zonal flow dominated states is investigated by varying the ion temperature gradient in nonlinear gyrokinetic simulations. Independent gradient…
Anisotropic truncation for turbulent transport and zonal flows in the Hasegawa-Wakatani system
Pierre L. Guillon, Robin Angles, Yanick Sarazin +1
Reduced models based on an anisotropic truncation of the Fourier space, retaining only a few poloidal wave-numbers while keeping the full radial resolution, are developed and first…
