摘要
The hydrodynamic equations describing wall plasma turbulence resulting from the nonlinear dynamics of the dissipative g-mode are analyzed numerically. The effect of the poloidal sheared flow on turbulent transport is studied, and the turbulent diffusion coefficient is investigated as a function of the Peclet number. It is shown that the radial current at the plasma edge may play an important role in triggering the L-H transition.
