Research Abstract

The toroidal flow generation by the ICRF minority heating is investigated numerically in the Alcator C-mod like plasma. We find that there exist two kinds of toroidal flow driving mechanisms. It is found that the k// sign dependent flow would be related to the mechanism proposed by Ohkawa et al., and that the k// sign independent one is generated by the net toroidal motion of energetic tail ions.
