“…However, the effects of the nozzle aperture diameter, various pressing forces on the ejection of the water molecules and separation of the nanoscale water droplets have rarely been investigated. This paper is a continuation of a previous study [15] using MD simulation methods to investigate the separation of nanoscale water droplets from the nozzle plate surface and the causes of separation of the nanoscale water droplet from the nozzle plate surface were also investigated and discussed. Furthermore, cursory observations on the impingement of nanoscale water droplets onto a fixed metallic plate are described.…”

Abstract. This paper studies the water nanojet ejection process using molecular dynamics simulation. The results show that nanoscale water droplets cannot separate from the nozzle plate surface when the nozzle aperture has a diameter of 27.5 Å or smaller. The maximum height of the produced water nanojet is reduced after reaching to its highest position when the jet does not separate from the plate surface. Separation phenomenon between the water nanojet and the nozzle plate surface is the most obvious with the 27.5-Å-diameter nozzle aperture for this simulation setup. In addition, initial findings on the characteristics of nanoscale water droplets (width and contact angle) impinging onto a fixed plate surface are revealed in preparation for future investigation.

“…While many studies focus on fluid nanojet ejection, breakup, droplet formation, collisions among nanojets, and coalescence on solid plates, the effects of temperature and nozzle diameter on the separation of nanoscale water droplets from a nozzle plate surface, as well as the influence of various pressing forces on nanoscale droplet impingement on fixed and moving solid plates, remain relatively unexplored. This research builds upon previous work using MD simulation methods to describe the water nanojet ejection process [48]. It investigates the causes of nanoscale water droplet separation from the nozzle plate surface and examines nanoscale droplet impingement on fixed and moving metallic plates.…”

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.
