Multi-scale transport simulation of internal transport barrier formation and collapse

Description

The mechanism of internal transport barrier (ITB) collapse in the reversed shear configuration is investigated using a global Ion Temperature Gradient driven drift wave (ITG) turbulence code. The toroidal momentum source (TMS) is introduced to follow the self-consistent evolutions of the ion temperature and flow profiles. Using a new code, we investigated the Toroidal Flow Shear (TFS) effect on the dynamics of ITB evolution. It is found that the enhancement of lifetime of ITB occurs by TFS effect. (author)
