In order to clarify the influence of impact parameters on the flattening process of a high-temperature, high-speed droplet due to its impact on a substrate in an atomic level, several 3-D molecular dynamics simulations were conducted. The droplet and the substrate were assumed to consist of pure aluminum, and Morse potential was postulated between a pair of aluminum atoms. In this report, the influence of impact parameters, such as impact speed and droplet size on the flattening behavior of a droplet was analyzed. As a result, it was clarified that the flattening ratio increases in proportion to impact speed and droplet size, and it was also understood that the solidification morphology is affected by impact speed, and so on.
Summary: To clarify the influence of impact parameters on the flattening process of a high-temperature, high-speed droplet due to its impact on a substrate in an atomic level, several 3-D molecular dynamics simulations were conducted.
