title = "Effects of grain size and grain shape in granular flow simulations",
abstract = "A model test of granular flow was reproduced using DEM. Some calculation cases with different grain sizes were performed to investigate effects of grain size. Effects of grain shape were also investigated by using spherical elements and non-spherical elements. According to obtained results, non-spherical and enough small elements could reproduce entire flow behavior obtained in the model test. The important thing in granular flow simulations is not to describe real grain size and grain shape, but to use enough small elements and to consider grain shape roughly. It is very important to figure out criteria of element size and degree of shape representation for use of DEM at practical level.",
