TL;DR: In this article, a detailed comparative analysis between classical analytical methods and discrete element method (DEM) is presented to predict the flow mechanisms associated with the deformation of granular material impacting a flat plate.

TL;DR: In this article, the authors describe some of the bench-scale experiments that have been developed to calibrate the discrete element method (DEM) simulations to reflect actual dynamic behaviour, such as static and rolling coefficients of friction, coefficient of restitution and interparticle cohesion forces from the presence of liquid bridges.

TL;DR: In this paper, a new test-design procedure is presented for low-velocity slug flow pneumatic conveying, based on particle properties and data from a simple vertical test chamber, which can be applied to bulk solid materials with regular, irregular and/or unusual physical properties.

TL;DR: In this paper, the capacity limitation of low-velocity slug-flow pneumatic conveying is investigated and a new theoretical model based on observed unstable flow mechanisms and stability criteria is presented for the purpose of predicting transport boundaries.

TL;DR: In this article, the authors present results from investigations into quantifying and modelling the dust generation and air entrainment mechanisms that occur during free-falling streams of material, focusing on the effects of drop height and product temperature.
