Towards an emerging understanding of non-locality phenomena and non-local transport

[摘要] In this paper, recent progress on experimental analysis and theoretical models for non-local transport (non-Fickian fluxes inreal space) is reviewed. The non-locality in the heat and momentum transport observed in the plasma, the departures fromlinear flux-gradient proportionality, and externally triggered non-local transport phenomena are described in both L-modeand improved-mode plasmas. Ongoing evaluation of ‘fast front’ and ‘intrinsically non-local’ models, and their success incomparisons with experimental data, are discussed.
