Global Gyrokinetic Simulation of Tokamak Transport
نویسندگان
چکیده
A kinetic simulation code based on the gyrokinetic ion dynamics in global general metric (including a tokamak with circular or noncircular cross–section) has been developed. This gyrokinetic simulation is capable of examining the global and semi–global driftwave structures and their associated transport in a tokamak plasma. We investigate the property of the ion temperature gradient (ITG) or ηi(ηi ≡ ∂`nTi/∂`nni) driven drift waves in a tokamak plasma. The emergent semi–global drift wave modes give rise to thermal transport characterized by the Bohm scaling.

Full f gyrokinetic simulation of transpor t in tokamak plasmas
Introduction: The electromagnetic gyrokinetic (GK) plasma simulation [1] for toroidal magnetic fusion devices has become a standard tool for turbulence analysis. Recently, it has been recognized that transport involving dynamic changes in profiles requires modelling with full f GK methods [2]. In the present work, we report on transport simulations for the FT-2 tokamak plasma with a full f nonl...

Gyrokinetic simulation of tokamak transport has evolved sufficiently to allow direct comparison of numerical results with experimental data. It is to be emphasized that only with the simultaneous inclusion of many distinct and complex effects can this comparison realistically be made. Until now, numerical studies of tokamak microturbulence have been restricted to either (a) flux tubes or (b) el...

The fluid-kinetic hybrid electron model is verified in global gyrokinetic particle simulation of linear electromagnetic drift-Alfv enic instabilities in tokamak. In particular, we have recovered the b-stabilization of the ion temperature gradient mode, transition to collisionless trapped electron mode, and the onset of kinetic ballooning mode as be (ratio of electron kinetic pressure to magneti...
