Solutions of the Navier-Stokes Equation Through Affine Transformations: The Triad Triplet
Ö. D. Gürcan, L. Manfredini, P. Morel
Considering triads in helical decomposition of three dimensional Navier-Stokes turbulence, three consecutive triads of the same shape and class, where the reference wave-number app…
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…
Flux-driven turbulent transport using penalisation in the Hasegawa-Wakatani system
Pierre L. Guillon, Özgür D. Gürcan, Guilhem Dif-Pradalier +2
First numerical results from the newly-developed pseudo-spectral code P-FLARE (Penalised FLux-driven Algorithm for REduced models) are presented. This flux-driven turbulence/transp…
Phase and amplitude evolution in the network of triadic interactions of the Hasegawa-Wakatani system
Ö. D. Gürcan, J. Anderson, S. Moradi +2
Hasegawa-Wakatani system, commonly used as a toy model of dissipative drift waves in fusion devices is revisited with considerations of phase and amplitude dynamics of its triadic…
