| Abstract: | Applying periodic boundary conditions to DEM simulations of granular motion in horizontal, rotating cylinders can result in
unexpected bulk axial flow. This axial flow is shown to contribute significantly to the mean square deviation in particle
position and consequently must be considered in the analysis of processes governed by slow axial motion such as axial dispersion. |
