Molecular dynamics simulation of the nano–ejection system with various interfacial wettabilities
Because of the significance of the interfacial phenomenon, this study examines the nanojet ejection systems with various interfacial wettabilities. A modified Lennard–Jones potential function was used to simulate the various solid–liquid interfacials from strongly hydrophilic to strongly hydrophobic. The properties distributions with various hydrophilic/hydrophobic interfaces are shown and discussed. The results show that decreased degree of hydrophilic interaction between solid–liquid molecules will promote the liquid injection through a nozzle. But the ejection systems are similar in the hydrophobic cases. Results that illustrate various features are presented to aid in the comprehension of the nanojet systems.
