Abstract
We investigated single droplet impingement to a solid wall by the MPS-AS method. The MPS-AS method was a unified particle method based on the MPS method for both compressible and incompressible flows. The speed and the profile of the shock wave from the impact point agreed well with the experimental result by Field et al. The shock reflection from the droplet surface was also captured. The same tendency as Rochester's experimental approximation was obtained with respect to the peak pressure.
