Packing of rod particles by tapping
WebFeb 5, 2009 · Random packings of non-spherical granular particles are simulated by combining mechanical contraction and molecular dynamics, to determine contact numbers as a function of density. Particle shapes are varied from spheres to thin rods. The observed contact numbers (and packing densities) agree well with experiments on granular … Websurface roughness where the rod contacts the packing rings. Piston rods wear more slowly than packing rings, having a life of about 10 years. Rods wear “out-of-round” or taper when …
