抄録: | The saltation of fine particles on an obliquely oscillating plate was simulated using a mass-point model that considered the gravity, fluid resistance, restitution, and friction. To examine the effects of the restitution and fluid resistance on the horizontal transport velocity, the two-dimensional movements of three particles with different coefficients of restitution and diameters were calculated. The results showed that a particle with a higher restitution and smaller diameter had a smaller transport velocity. This can be explained as follows. A particle with a higher restitution bounces forward and backward repeatedly, whereas a particle with a lower restitution only bounces forward, because the higher bounce height increases the impulse exerted on the particle during a collision, which induces a drastic change in the horizontal velocity from the collision. The horizontal velocity of a smaller particle is decreased by the drag force during its flight between successive collisions. |
