In this study, we investigate the growth mechanism of bubble nuclei and the exponent forcoarsening rate of the mean radiususing microcanonical molecular dynamics simulation. The coarsening process of the bubble nuclei such as Ostwald ripening occurs in the case of one-component liquid while it is not observed clearly in the case that noncondensable gas forms bubble nuclei. Although the same coarsening rate (n=1/2) is obtained, we confirm the different characteristics of the change of the total radius and the decrease of the bubble nuclei with coarsening. We describe the differences reflect the characteristics of the radius change of each nucleus and the size distribution function.
