Abstract

In order to decide the life time of the divertor plate of fusion reactors, it is necessary to estimate the erosion loss during a plasma disruption. However, in order to realistically simulate the effects of the plasma disruption on the plasma facing components, every related physical process should be taken into account, but it found to be difficult to be solved. The molecular dynamics method is one of the alternative and effective numerical methods to make it possible to analyze such the non-equilibrium phase change problems. In this study, the nonequilibrium evaporation processes are simulated with using the molecular dynamics method. Velocity distributions of evaporating atoms are analyzed.
