A Molecular Dynamics Study on the Growth of Bubble Nuclei with a Noncondensable Gas

2nd Report, An Extraction of a Growth Law of the Bubble Nuclei

Abstract

In this report, we have extracted the exponent for coarsening rate of the mean radius of the bubble nuclei using microcanonical molecular dynamics simulations. The objects of the simulations are one-component liquid argon and liquid argon with a moncondensable gas, as in the case of the 1st report. Although the same coarsening rate (n=1/2) was obtained between the two cases, we have confirmed that the different characteristics are reflected in the change of the total radius and in the change of the number of the nuclei with the coarsening. We show that the differences reflect the characteristics of the radius change of each nucleus and those of the size distribution function.
