| Research Abstract |
The purpose of this study is to construct global transport mode in toroidal plasmas. There are two branches of zonal flows ; stationary and oscillatory zonal flows(ZF, GAM, respectively). The turbulence transport model that can describe the nonlinear coupling between GAMs and ZFs is formulated, which is the progress towards the global transport model. The effect of plasma boundary is introduced in the turbulence-zonal flows model, and the possibility of generation of macro-scale mean flow is discussed. The novel ion heating method is also proposed, in which the GAMs driven by energetic particles heat ions through Landau damping.
