Molecular dynamics simulation of the nano ejection system with various interfacial wettabilities

This study investigates the performance of nano ejection systems by molecular dynamic simulation. The results show that decrease the degree of hydrophilic between solid-liquid molecules will promote the liquid injection through a nozzle. But the ejection processes are similar in the hydrophobic cases. Density distribution and energy evolutions are shown and discussed. Results that illustrate various features are presented to aid in the comprehension of the nanojet processes.
