Description
The dynamics and spreading of nano water droplets on different surfaces have received significant attention due to their potential applications, such as self-cleaning surfaces, water condensation in solids, water collection and transportation, heat transfer during condensation, and energy harvesting. Changes in the wettability of surfaces can have considerable consequences on nanofluid properties, making the application of wetting control parameters useful in designing related nanofluid devices. Atomistic simulation methods, such as the molecular dynamics (MD) simulation method, provide a powerful approach to studying these phenomena and can be useful in exploring the dynamics of nano droplets. These simulations enable researchers to investigate the behavior of water droplets and control their movement by changing or applying suitable physical parameters, such as external electromagnetic fields. In this study, we utilized the MD simulation method to explore the dynamics of droplets on different surfaces and attempted to control their behavior by applying external electric fields or altering surface properties, such as hydrophilicity. The results of the simulations demonstrate that by adjusting environmental parameters, the movement of the droplets can be controlled, and directional movement or even jumping of the droplets can be observed on the surface. Furthermore, the effects of applying constant electric fields on the dynamics of a confined water droplet between two different surfaces were investigated. The findings of these studies can be applied in heat transfer control, cleanliness, material transfer, and filter design.
