| Research Abstract |
Pellet injection is the most promising technique for fueling magnetic fusion reactors. In this study, the pellet ablation and density homogenization processes have been investigated and modeled for evaluating mass deposition profiles of hydrogen pellets injected into the Large Helical Device(LHD). A simulation code that takes into account ablation of solid hydrogen, formation of dense plasma cloud, and drift motion of a deposited cloud was developed. A progress has been made in validating the developed model against the experimental results. It was shown that simulation results well reproduce main characteristics of the measured ablation and deposition profiles in the LHD.
