MOLECULAR DYNAMICS STUDY OF HEAT AND MASS TRANSFER FOR DISRUPTION EROSION
Sinopsis
In order to decide the life time of the divertor plate, it is necessary to estimate the erosion loss during a plasma disruption. However, in order to realistically simulate the effects of a plasma disruption on the plasma facing components, several physical processes should be taken into account. The molecular dynamics method is one of the effective numerical methods of analyzing non-equilibrium phase change problems. In this study, a numerical method based on molecular dynamics has been investigated with divided time interval, in order to simulate a system which contains a few atoms of high energy in most of slow atoms. Non-equilibrium evaporation processes are simulated by this method. Velocity distributions of evaporating atoms are analyzed.
