Liwei Sun, Xiaochun Pan, Jiachao Gu, Baocheng Zhan
TL;DR
This paper uses molecular dynamics simulations to study how nanodroplets behave when they impact solid surfaces, focusing on their spreading and contact time.
Contribution
The study provides new insights into the dynamic behavior of impacting binary nanodroplets at the nanoscale using molecular dynamics simulations.
Findings
The maximum spreading of binary nanodroplets during coalescence and on solid surfaces was analyzed.
Contact time of the systems was evaluated across a range of Weber numbers and contact angles.
The study offers guidelines for controlling nanodroplet spreading and detachment in industrial applications.
Abstract
The impingement of binary droplets upon solid surfaces has received growing attention in recent years because of its wide applications in industry. Although the dynamic evolution of impacting single droplets is relatively well satisfied, the understanding of impacting binary droplets remains inadequate, especially at the nanoscale. This paper uses molecular dynamics (MD) simulations to investigate the impact behavior of suspending nanodroplets with coming nanoscale ones to address this gap. The wettability of solid surfaces and the impact We are selected in a wide range to obtain an overall insight into the impingement of targeted systems. Firstly, the representative dynamics are recognized from snapshots to observe the corresponding instantaneous evolution at the molecular level. Secondly, the maximum spreading of impacting binary droplets during coalescence (primary spreading) and…
