DOI: 10.1016/j.ijsrc.2016.09.001
Abstract: Abstract In the investigation of sediment transport, it is necessary to differentiate various definitions of angle of repose (AoR) available in the literature. The static AoR, composed of upper and lower angle of slope, forms… read more here.

DOI: 10.1016/j.powtec.2018.01.044
Abstract: Abstract The numerical effort of computer simulations based on the Discrete Element Method (DEM) forces an idealisation of the DEM models especially when industrial problems are analysed. The idealisation often includes the scale-up of the… read more here.

DOI: 10.1016/j.powtec.2020.10.077
Abstract: Abstract Bulk solids commonly segregate when particles move on an inclined surface, often causing significant variations in content uniformity of particle properties such as size and species. Often called free surface rolling segregation, this is… read more here.

DOI: 10.3390/ma10050520
Abstract: Aiming at predicting what happens in reality inside mills, the contact parameters of iron ore particles for discrete element method (DEM) simulations should be determined accurately. To allow the irregular shape to be accurately determined,… read more here.
