MHD Computational Study on Pellet Injection

A fluid code is developed to study pellet injection into magnetically confined plasma. Since there are large differences between orders of pellet and plasma quantities, the code uses the Cubic-Interpolated Psudoparticle method that gives stable and less diffusive results. It is successfully applied to a one dimensional shock-tube problem. In result, when a cold plasma is in a hot plasma, a shock wave is driven toward the hot plasma and an ablation-like structure is induced between the cold plasma surface and the shock front.
