The role of thermal fluctuations on the formation and stability of nano-scale drops

Studying the Influences of Temperature to the Liquid Ejection and Nanodroplet Formation

The influences of temperature parameter for various values of 310[Formula: see text]K, 315[Formula: see text]K and 333[Formula: see text]K (Kelvin (K)) to liquid ejection through nozzle under the same magnitudes of nozzle diameter of 27.5 Angstrom (Å) and pressing force of [Formula: see text] Newton (N) were performed in this study by adopting the molecular dynamics simulation method. For the temperature values, almost all molecules were ejected out of the container through the nozzle and built up the liquid nanojets on the nozzle plate’s surface. Only the liquid jets separate out from the nozzle to form the nanodroplets for the temperature values of greater than or equal to 315[Formula: see text]K. Otherwise, the liquid nanodroplets were not formed for the case of temperature magnitude of 310[Formula: see text]K. Moreover, the witnesses are also provided in this research to explain for the separation of the nanojets from the nozzle plate’s surface to form the liquid nanodroplet.
