Research Abstract

The neoclassical toroidal viscosity is investigated in the three dimensional magnetic configurations; tokamaks with ripple field, error field, ELM control field and etc. First, we improve the GNET code to increase the efficiency of the parallel computing and to introduce the toroidal momentum conserving collision operator. Next, we study the neoclassical troidal viscosity with the magnetic perturbations of low to middle mode number and make clear the dependencies of the viscosity on the mode number and the collision frequency.
