Peridynamic modelling of cryogenic deuterium pellet fragmentation for shattered pellet injection in tokamaks
Shattered pellet injection (SPI) is a promising method for controlling plasma disruptions in tokamaks.In this study, we present numerical modelling of the fragmentation of Mask cryogenic deuterium pellets within the context of SPI, using the peridynamic (PD) theory.A dedicated in-house code has been developed, leveraging the meshfree method and GPU
