Moving Particle Semi-Implicit (MPS) Method has an advantage over traditional mesh-based methods in accurately trace the vapor-liquid interface. In this study, we had performed a numerical simulation of single steam bubble condensation behavior. Numerical results showed a good agreement with Kamei's experiments and indicated that there is approximately a linear relationship between bubble initial size and bubble lifetime. A larger bubble condensation process would be accelerated by its deformation at lower degrees of liquid subcooling while the bubble condensation would induce oscillation at higher subcooling degrees. Furthermore, numerical investigation on coalescence of bubble pairs rising in the stationary liquid had been performed. The numerical results were provided for bubble shape deformation and rising velocity before and after coalescence. The present study exhibits some fundamental characteristics of steam bubble condensation and bubble pairs coalescence. It is also lay the foundation for further application of the MPS method to evaluate more complicated bubble dynamics problems.
