Using non-equilibrium molecular dynamics, argon nanojet injection was simulated under vacuum conditions. A series of simulations with different shapes of solid platinum injectors was conducted. Observed droplet sizes and jet break-up characteristics resemble the Rayleigh break-up theory. However, the different injector shapes did not cause a significant change in the nanojet break-up behaviour. The liquid temperature inside the injector was found to be a controlling factor in determining the subsequent break-up characteristics. A higher liquid temperature is preferred for the faster nanojet break-up with the shorter break-up length.
