model of interchange turbulent transport: on the correlation between scrape off layer width and core confinement in tokamaks

Résumé

 Spectral filament paradigm: self consistent prediction of turbulent spectra (, Φ) of flux driven 2D isothermal interchange turbulence  Predicts macroscopic transport properties (flux, fluctuations) in scrape-off layer ( SOL width) but also in the core ( confinement time)  SOL transport: quantitative agreement with Tore Supra data (circular plasmas), recovers impact of divertor leg length on SOL width () in TCV, recovers multi-machine parametric sensitivity of  Core confinement: recovers multi-machine parametric sensitivity of and correlation between core confinement and heat flux width  Offers a flexible paradigm for addressing the optimization of power exhaust versus core confinement (key: impact of geometry in model) 2D isothermal interchange model (TOKAM2D)
