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…
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…
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…
Gyrokinetic investigation of Alfvén instabilities in the presence of turbulence
A. Biancalani, A. Bottino, A. Di Siena +10
The nonlinear dynamics of beta-induced Alfvén Eigenmodes (BAE) driven by energetic particles (EP) in the presence of ion-temperature-gradient (ITG) turbulence is investigated, by m…
A Differential Approximation Model For Passive Scalar Turbulence
Pierre Morel, Shaokang Xu, Özgür D. Gürcan
Two dimensional passive scalar turbulence is studied by means of a k-space diffusion model based on a third order differential approximation. This simple description of local nonli…
Spiral chains in wavenumber space of two dimensional turbulence
Ö. D. Gürcan, Shaokang Xu, P. Morel
Abstract Self-similar, fractal nature of turbulence is discussed in the context of two dimensional turbulence, by considering the fractal structure of the wave-number domain using…
