Investigating the Influence of Ejection Diameter Size Parameter to Liquid Ejection by Molecular Dynamics Simulation Method

Van Quang Nguyen, Trong Ly Nguyen

Abstract: The research adopts the molecular dynamics simulation method to simulate the liquid molecule ejection through different ejection diameter sizes of 25 Ã… and 40 Ã… and pushing force 11.0 10-10 N. The obtained simulative results conclude that almost liquid molecules eject out through the hole diameter of 40 Ã… to build up liquid jet and then produce nanoscale droplets. Contrarily, the liquid molecules after ejecting out the container could not go away the top plate for the hole diameter of 25 Ã… under same the magnitude of pushing force.
