Low dimensional model of ion temperature gradient driven turbulence
Description
A complex Lorenz system is derived for toroidal ion temperature gradient driven drift wave turbulence. For tokamak relevant parameter values, the system evolves towards a nonlinear equilibrium where analytical expressions for the saturation levels and for the ion diffusion coefficient are obtained. The low-dimensional system is found to reproduce many essential properties of the full set as known from nonlinear numerical simulations
