The growth of formed bubble nuclei (with solute gas molecules) is simulated by the microcanonical molecular dynamics method using the larger computational domain. In the case of pure liquid argon, after some nuclei of vaporization are formed, neighbor nuclei compete with each other, and the larger ones continue to grow while the smaller ones start to collapse along the way. On the other hand, when a gas (whose potential parameters are those of helium) is dissolved at a high concentration, many nuclei of phase separation are formed, and their coalescence continuously occurs. Here, we observed that the growth mechanism of bubble nuclei are inherently different between vaporization (pure liquid) and phase separation (liquid-gas mixture).
