Isotope effect on blob-statistics in gyrofluid simulations of scrape-off layer turbulence
arXiv:1705.10641 · doi:10.1088/1741-4326/aa8e33
Abstract
We investigate time-series obtained from gyrofluid simulations in coupled edge/scrape-off layer turbulence characteristic for fusion edge-region plasmas. Blob birth near the separatrix produces intermittent signals whose statistics depend on the ion mass of the reactor fuel, pointing towards overall slower dynamics for heavier isotopes. We find that a recently established shot-noise stochastic model for scrape-off layer fluctuations coincides reasonably well with the numerical simulations performed in this contribution.
