“…The effects of temperature and aperture size parameters on the liquid ejection process by using molecular dynamics simulation were performed [13]. According to the analysis, the Nano-jet aperture is distributed as the temperature is increased under these effects [14]. The fluidic-droplet formation behavior was also investigated with two fluid types of water and ethylene glycol [15,16].…”

This paper studies the liquid Nano-droplet production ability using molecular dynamics simulation methodology. The research parameter is performed at the temperature of 310 Kelvin (K), the pressing force of 10.0 × 10−10 Newton (N) and the ejective hole diameters of 25 and 40 Angstrom (Å). The research result shows that liquid Nano-droplets finally were not produced for the ejective diameter of 25 Å. The Nano-jets were not only non-destruction from nozzle’s surface to produce the droplets but also movement downward to come back the nozzle’s surface. The molecular trajectory is very zigzag and curved both inside and outside the ejective container. In the contrary, when increasing the ejective diameter to 40 Å, the liquid Nano-droplet was produced in the same the ejective time and compressible force magnitude. The molecular trajectory is quite straight after ejecting out the outside of the container. Meanwhile, for the nozzle diameter size of 40 Å, the Nano-droplet was not only production but also movement up to leave away the nozzle’s surface under same above conditions. That proves that the ejective diameter has the influences to the moveable direction and Nano-droplets formation ability in the whole ejective process.

This study employs molecular dynamics simulations to investigate the ejection of nanoscale fluidic molecules through different nozzle apertures under various technology parameters. The model comprises a nozzle plate, a back plate, and water molecules filling the space between them. LAMMPS software and C + + code are used for simulations and data analysis. The research explores the impact of system temperature and nozzle aperture diameter on water droplet separation from the nozzle plate surface. It also delves into the effects of environmental parameters on nano droplet formation. The results indicate that the separation of nanoscale fluidic droplets is performed under the effect of nozzle aperture, the system temperature and ejection time but regardless of pressing forces. Additionally, the study investigates the influence of various pressing forces on the impingement of these droplets onto fixed metal plate’s surface under different system temperatures. The findings provide essential data for experimental and manufacturing processes utilizing this technology, with potential applications in fields like printing, printed circuit board manufacturing, and the development of nanoprinters, nanosprayers, and nanomachining devices.

The molecular dynamics is the research method which is used to simulate the liquid ejection in this paper. The factors of 200000 time step (fs) total ejective time of total 200 000 time steps (fs) and various compressible forces of 9.0 × 10−10, 10.0 × 10−10 and 11.0 × 10−10 Newton (N) are main investigated in this research. These influences have action to the moveable direction of fluid jet in the whole ejective process. The research result indicates that liquid jet is prepared to separate out from nozzle plate's surface to form up droplets at the ejective time of 140 000 fs for the nozzle diameter size of 27.5 Angstrom (Å), system temperature of 310 Kelvin (K) and compressible force magnitude of 9.0 × 10−10 (N). However, when increasing the ejective time or compressible force magnitude, the jets were not only non-destruction from nozzle's surface to produce the droplets but also downward movement to go back the nozzle's surface. Meanwhile, with the nozzle diameter size of 40 Å, the droplets are not only production but also movement up to go away the nozzle under same research condition. Those prove that the ejective time and compressible force magnitude have the influences to the moveable direction of fluid jet in the whole ejective process.
