The resistive interchange convection in the edge of tokamak plasmasFunded under: FP3-FUSION 11C
This paper summarises earlier and recent theoretical results concerning the behaviour of plasmas outside the separatrix. The resistive interchange model is used to describe the generation of poloidal (or toroidal) flow and the onset of ELMs, which appear as bubbles of increased density (or higher temperature). The decrease of the turbulent transport processes as the velocity of the flow increases and its connection with the L-H transition are discussed. Analytic solutions for asymptotically small parameters in the nonlinear model are derived. Semi-phenomenological turbulence balance equations for the resistive interchange convection are also presented. Finally, these results are applied for the explanation of existing experimental results.
