Abstract
A detailed experiment investigation of rebound trajectory of impinging particle on a flat plate was carried out using Ar+ laser and a camera. The jet velocity was 6.9 m/s and 15 m/s, and three kinds of glass beads of 30, 58 and 100 μm in diameter were used. The photographs of particle motion trajectory show that the impingement and the rebound depend on the momentum of particle: and the secondimpingement depends on the particle diameter and the entrainment velocity of environment air. The particle motion near the plate shows a rounded trajectory in radial direction by air flow along the wall.
