A Numerical Simulation of Bouncing between Particle and Plate and Its Application to Pneumatic Conveying

Abstract

The scattering of coefficients of restitution and friction, which is often observed in experiments is studied numerically by using a new bouncing model. This model can be applied to the bouncing of particles of arbitrary shape. Numerical simulation shows that the scattering is largely affected by particle shape and that irregular bouncing and Stick-Slip phenomena of particles in horizontal pneumatic conveying are explained by the present model.
