Molecular dynamics investigation of nanoscale cavitation dynamics

Abstract: We use molecular dynamics simulations to investigate the cavitation dynamics around intensely heated solid nanoparticles immersed in a model Lennard-Jones fluid. Specifically, we study the temporal evolution of vapor nanobubbles that form around the solid nanoparticles heated over ps time scale and provide a detail description of the following vapor formation and collapse. For 8 nm diameter nanoparticles we observe the formation of vapor bubbles when the liquid temperature 0.5-1 nm away from the nanoparticle s… Show more

“…This analysis was confirmed by a molecular dynamics (MD) study in Ref. [10], and the good behavior of the macroscopic Rayleigh-Plesset theory opens the question of a thermodynamic macroscopic-like description of the nanobubble. MD is a very valuable approach because it allows a molecular-scale description of the phenomena with simple assumptions on the molecular interactions.…”
