Description
This paper discusses the movements and rearrangements of about 30,000 sand particles due to the impact of a water-drop using a multiphase computational method (MICS) parallelized with MPI. The computational method can deal with the movements and collisions of individual sand particles as well as the mechanical interaction between fluids and sand particles. The amounts of the removed volumes, which had been occupied by sand particles, due to the impact were calculated by varying the momentums and shapes of the water-drop. As a result, it was shown that the calculated results are in good agreement with the experiments and that the computation time is shortened by the parallel computations.
