Classic Nucleation Theory

The bubble homogeneous nucleation in superheated liquid argon is studied by molecular dynamics simulation in NVT ensemble. L-J potential is adopted for the interaction of argon atom. The simulated particle numbers of argon atom is 10976. The non-dimensional size of simulated box is 27.8×27.8×27.8. The initial non-dimensional temperature and density are 0.4 and 0.51 separately. The results show that the bubble homogeneous nucleation is divided into the waiting process, the appearing process of numerous small bubble nucleuses and the aggregation process of small bubble nucleuses. By fitting simulated data, we find that the bubble nucleation rate is eight orders of magnitudes bigger than the result of classic nucleation theory. The bubble nucleation rate increases along with the increasing of density and superheated temperature, which agrees well with one of classic nucleation theory.

Cavitation Nuclei

The transient properties of liquid argon cavitation nuclei in platinum surface were studied by means of molecular dynamics simulation. The bubble nucleation, with a certain size and stability on the wall surface, was studied by different tensile distances and different wall wettabilities. Also the parameters of cavitation nuclei development, the system pressure, and the total pressure were analysed. The stability of cavitating nucleus growth is closely related to the metastable degree of the system and the wettability of the wall. The tensile distance of the wall surface has a critical value, and stretching greater than the critical value will induce a greater degree of instability in the system, which is conducive to the growth of the cavitation nucleus. A hydrophobic wall is more conducive to the growth of a cavitation nucleus, which is beneficial to spontaneous growth among cavitated nuclei, whereas a hydrophobic exerts has an inhibitory influence on cavitation nuclei.
