英文摘要Edge fluid-plasma/kinetic-neutral SOLPS [1, 2] modeling of lithium (Li) transport and its effect on the edge plasma during real-time Li injection H-mode discharge on the EAST tokamak are analysed in this work. Since Li has strong chemical activity, deuterium (D) recycling is suppressed by a Li coated plasma-facing wall. By comparing the simulated edge plasma parameters between the no Li case and the Li injection case, it is found that both of the D atom and molecule densities in the divertor region are reduced with the Li injection. It is also found that most of the radiated power is radiated in the divertor. The simulation provides and analyzes the distributions of each Li ion charge state, and the evolution of Li impurity distribution. The simulation shows that the Li+ prefers to accumulate on the high-field side than on the low-field side, which is in qualitative agreement with the experimental measurements on EAST. The possible reason for the Li+ preferential accumulation is discussed in this study.
