Effects of temperature and aperture size on nanojet ejection process by molecular dynamics simulation

摘要

This paper studies the effects of temperature and aperture size on the nanojet ejection process by means of molecular dynamics simulation using the Lennard-Jones potential. According to the analysis, it can be seen that the spurting atoms from the nanojet aperture are more evenly distributed as the temperature is increased. However, as the temperature lowers, the atoms easily concentrate on the central region. Furthermore, when a larger nanojet aperture was used, the amount of spurting atoms increased and concentrated easily into the central region. The phenomenon of the pressure wave was found with the aid of molecular dynamics.
