Simulation of deformation and disruption of a droplet with SPH for incompressible fluid

Abstract

In the study of the formation of chondrule, it is important to explain the observed distribution of its size. Especially, it is difficult to quantitatively estimate the maximal size of chondrule, since the complicate effects of deformation and disruption are included. Therefore we performed two-dimensional simulation of deformation and disruption of a droplet with SPH for incompressible fluid. In this simulation, we adopted the effect of the surface tension. Using this simulation, it was confirmed that whether a drop was deformed or disrupted was dependent on the Weber number. Our results will be used to quantitatively investigate the distribution of maximal size of chondrule in shock wave heating model.
