Scrape-off layer turbulence theory and simulations

PDF Version Also Available for Download.

Description

Significant investigations in the area of scrape-off layer (SOL) turbulence theory and simulations are reviewed. The review begins with description and derivation of the various models investigating specific linear modes as well as a discussion of the region of validity. Special attention is focused on various low-frequency electromagnetic drift-types modes in an x-point divertor geometry, which are generally believed to be relevant under normal operating conditions for current and future large fusion devices. Benchmarks of linear ballooning codes with nonlinear 3D fluid code will be given. The anomalous transport from simulations and mixing length estimates are discussed` and a summary ... continued below

Benchmarks of linear ballooning codes with nonlinear 3D fluid code will be given. The anomalous transport from simulations and mixing length estimates are discussed` and a summary of relevant experimental results as well as empirical values in the transport codes are given. Studies of mechanisms for the L-H transition due to turbulent transport in the SOL and its impact on the the H-mode power threshold are also surveyed.
