Research Abstract |
Phenomena such as heat transfer are called "nonequilibrium" phenomena. Physical understanding of the nonequilibrium phenomena is still poor, even though the phenomena are ubiquitous in nature. In this study, we investigate the nonequilibrium phenomena by the computer simulation for understanding; Especially, dynamics and structural formation of bubbles under rapid decompression, fracture dynamics caused by shrinkage, and dynamics of a grain boundary under a thermal gradient are studied. The results may be applicable to control the nonequilibrium phenomena.
