Abstract

Investigations of lithium transport in H-mode plasma of EAST tokamak have been performed by the three-dimensional fluid code EMC3-EIRENE. The simulation results show that the toroidally-localized lithium injection at the low field side (LFS) leads to a toroidally non-axisymmetric distribution of the Li¹⁺ and Li²⁺ ions. The field line tracing approach is utilized to carry out a detailed study on the distributions of the Li¹⁺ and Li²⁺ ions. It is found that Li¹⁺ ions mainly reside at the LFS while Li²⁺ ions can transport from LFS to the high field side. The relationship between mean free path and connection length for Li¹⁺ and Li²⁺ ions has been discussed. The 3D line-integration images of deuterium and lithium emission spectra modelled by EMC3-EIRENE are in qualitative consistency with the experiment results.
