BOUT++ Movies

BOUT++ simulations reveal the dynamics of electron temperature filamentary eruptions of hot plasma from the edge during edge-localized mode crashes. Experimentally measured EAST tokamak profiles in ELMing H-mode have been used as input for BOUT++ simulations in a double null divertor configuration.

BOUT++ simulations reveal the dynamics of electron temperature filamentary eruptions of hot plasma from the edge during edge-localized mode crashes. Experimentally measured DIII-D tokamak profiles in ELMing H-mode have been used as input for BOUT++ simulations in a single null divertor configuration. The BOUT++ computed fluxes on divertor floor is found to match with experimentally measurement!

Experimentally measured C-Mod profiles in enhanced Dα (EDA) H-mode have been used as input for BOUT++ simulations in real X-point divertor geometry. The BOUT++ computed mode is found to propagate in the electron diamagnetic direction, which agrees with experimentally observed quasi-coherent mode (QCM) oscillation!
