Numerical study of transition between rolling and saltation movement of spherical particles

Original language description

Modelling of rolling and saltation movements of particles is dealt with, transition between rolling and saltation is described and the flow condition for it is found. This investigation is based on a suggestion that rolling might be considered as a saltation with small leaps. A numerical model of spherical particle saltation in turbulent flow in a channel is used and several criteria of difference between saltation and rolling modes based on both the average length and the average height of saltation leap were proposed.
