摘要: A critical event in the trajectory of a sand grain saltating air is its interaction with surface. We examine phenomenon grain-bed impacts two dimensions using combination dynamical computer simulations, analytical models and physical reasoning. The results indicate that collisions can be treated as two-body bed particle assuming an effective mass greater than true mass. Also, presence geometrical surface irregularities has strong bearing on between populations, well formation small-scale bedforms.
