Outline of Final Research Achievements

The equations based on the two-fluid model on the flux coordinates were derived and they were successfully implemented in a fluid-type transport code TASK/TX. TASK/TX is a unique code in that it can self-consistently deal with the evolution of both the electromagnetic fields and the plasma fluid. Improving the moment-approach-based neoclassical transport mode, we obtained the very good agreement between the measured radial electric field in the experiment and that predicted by the model. We have developed the numerical framework that can accurately calculate the neoclassical toroidal viscosity (NTV) due to non-axisymmetric perturbed magnetic fields. The framework makes it possible to analyze the NTV in experiments and predict toroidal rotation with the NTV. We have also been developing the brand-new framework that can calculate the kinetic profiles consistent with turbulent transport using the first-principle gyrokinetic code. The verification study has been successfully demonstrated.
