Résumé

This paper investigates Rayleigh’s instability of a liquid thread by molecular dynamics (MD) simulation. The influences of liquid thread radius, fundamental cell length, and temperature are discussed. Snapshots of molecules, number of liquid particles formed, and density field are analyzed. It is found that a liquid thread is more unstable and produces more liquid particles in the fundamental cell when it is thinner or at a higher temperature. In addition, a liquid thread with a longer fundamental cell length is also more unstable and produces more liquid particles in the fundamental cell, but it evaporates slower. The trend of Rayleigh’s stability criterion agrees with MD simulation results although it overpredicts stable domain as compared to the MD simulation results. Finally, a liquid thread with a higher time averaged density uniformity factor is more unstable and produces more liquid particles in the fundamental cell.
