The results show that, during the period of collision between the sand grain and the sand bed, the lost kinetic energy is more than half of the total energy. Moreover, because the percentage of collision angles with more than 0° is up to 70％, the vertical speed of sand increases even if the kinetic energy decreases, which ensures that the sand particles can receive more energy from the air to keep on the saltation movement.
