Influence of Thermodynamic State on Nanojet Break-up

Kurzfassung

Using a non-equilibrium molecular dynamics, argon nanojet injection was simulated under vacuum condition. A series of simulations with different shapes of solid platinum injectors were conducted. Observed droplet sizes and jet breakup characteristics resemble the Rayleigh breakup theory. However, the different injector shapes do not cause the remarkable change in nanojet breakup behaviour. The liquid temperature inside the injector is the controlling factor to determine the subsequent breakup characteristics. Higher liquid temperature is preferred for the faster nanojet breakup with the shorter breakup length.
