Abstract

Full-f gyrokinetic simulations compute both turbulent transport and profile formations under fixed power, momentum, and particle input as in experiments. This approach has the capability of dictating plasma profiles, provided that time scale of the simulation is long enough to establish power, momentum, and particle balance conditions. Recent Peta-scale supercomputers made such long time scale simulations feasible, and full-f gyrokinetic simulations are applied to reactor relevant numerical experiments. In this paper, physical models, numerical approaches, and accuracy issues of the gyrokinetic full-f Eulerian code GT5D are summarized, and then, its recent applications to the scaling studies of turbulent transport with respect to plasma size and heating power are reviewed.

Keywords

gyrokinetic theory, full-f Eulerian code, ion temperature gradient driven turbulence, plasma size scaling, power degradation of confinement
