In order to investigate a single vacuum bubble collapse near the free surface and the rigid boundary, the moving particle simulation (MPS) method has been used. Liquid and gas phase were defined by the moving particles and bobble shape was determined by the position of interface particle. The calculation was performed with four parameters; bubble radius, distances from free surface or rigid boundary to and viscosity of the liquid, to estimate the effect of these parameters on the bubble dynamics. The results showed that the bubble collapse time near the free surface is shortened, while the one with near the rigid boundary become prolonged. These four parameters significantly affect to the bubble interface velocity. To evaluate the accuracy of this model, the results are compared with the theoretical model and experimental results. A good agreement between present model and other results were obtained and validity of the present model to the vacuum bubble dynamics was confirmed.
