Molecular Dynamics Analysis on Impact Phenomenon of High–Temperature and High–Speed Droplet

Abstract

In order to clarify the flatting process of the high–temperature, high–speed droplet due to its impact on the substrate in an atomic level, a three–dimensional molecular dynamics simulation was performed. By visualizing the simulation results, the deformation and stress distribution of the substrate were investigated. As a result, it was clarified that the strain energy under the outside edge of the droplet became a little bit remarkable, while that under the center region of the droplet became not so remarkable because of sufficient plastic deformation.
