Compares rebound parameters for spheres and ellipsoids during impact, suggesting shape influences energy distribution.
The article investigates the influence of particle shape on its rebound parameters. A comparison is presented of the results of calculations of collision of particles in the shape of a sphere and an ellipsoid of revolution with a flat surface. It is shown that particle shape significantly affects the rebound parameters. It is found that the particle may interact with the surface more than once during impact, and a significant portion of the energy of the reflected particle is concentrated in the rotational degree of freedom ([9], Fig. 7).
