Complex Flow of Granular Material in a Rotating Cylinder
Thorsten Poeschel, Volkhard Buchholtz
The flow of granular material in a rotating cylinder was simulated by molecular dynamics in two dimensions using spherical as well as nonspherical grains. At very low but constant…
Force Distribution and Comminution in Ball Mills
Volkhard Buchholtz, Thorsten Poeschel
The motion of granular material in a ball mill is investigated using molecular dynamics simulations in two dimensions. In agreement with experimental observations by Rothkegel [1]…
Molecular dynamics of arbitrarily shaped granular particles
Thorsten Poeschel, Volkhard Buchholtz
We propose a new model for the description of complex granular particles and their interaction in molecular dynamics simulations of granular material in two dimensions. The grains…
Interaction of a granular stream with an obstacle
Volkhard Buchholtz, Thorsten Poeschel
We investigate numerically the interaction of a stream of granular particles with a resting obstacle in two dimensions. For the case of high stream velocity we find that the force…
