摘要：
A high-performance computation with billion scales of the explicit moving particle simulation method is successfully performed for the milk crown phenomena. Through the validation study regarding the size of the particle, it is confirmed that the appropriate size for realizing milk crown should be smaller than 0.05 mm. The simulation results are rather in good agreement with the experimental ones. Namely, the tiny droplet at the tip of the milk crown, which is called the spike, and the generation of spear-type splash, which is the secondary splash formed after the milk crown, are realized well as seen in the experiment.
