摘  要:

GTC simulations of DIII-D pedestal using the 3D equilibrium with closed flux surfaces reveal no increase of growth rates for the electrostatic drift wave instability and for the electromagnetic kinetic-ballooning mode in the presence of resonant magnetic perturbations. Furthermore, nonlinear electrostatic simulations show that the effect of the 3D equilibrium with closed flux surfaces on zonal flow damping is very weak and insufficient to modify turbulent transport in the electrostatic turbulence. GTC simulations of radio frequency waves in tokamak will also be presented.
