A numerical simulation of the L-H transition in JET with local and global models of anomalous transportFunded under: FP3-FUSION 11C
It has been shown experimentally that L-H transitions in JET have some features which cannot be described by a conventional picture in which the L-H transition initially manifests itself as a sudden reduction of anomalous transport coefficients near the plasma edge, followed by a slow improvement throughout the entire plasma on the energy confinement scale. The main aim of this work is to determine, on the basis of numerical simulation, which features the anomalous transport coefficients should contain in order to describe the experimental results. Special attention is given to the comparative study of local and global models of anomalous transport. The analysis of the results of the numerical study and conclusions are also presented.
