Abstract

15th International Workshop on Plasma Edge Theory in Fusion Devices (PET), Nara Kasugano Int Forum IRAKA, Nara, JAPAN, SEP 09-11, 2015International audienceThe impact of a 3D localized particle source on the edge plasma in 3D global turbulence simulations is investigated using the TOKAM3X fluid code. Results apply to advanced fueling methods such as Supersonic Molecular Beam Injection (SMBI) or pellets injection. The fueling source is imposed as a volumetric particle source in the simulations so that the physics leading to the ionization of particles and its localization are not taken into account. As already observed in experiments, the localized particle source strongly perturbs both turbulence and the large scale organization of the edge...
