Wood pellets are an important source of renewable energy. Their mechanical strength is a crucial property. In this study, the tensile strength of pellets made from oak, pine, and birch sawdust with moisture contents of 8% and 20% compacted at 60 and

Starch agglomerates are widely applied in the pharmaceutical, agricultural, and food industries. The formation of potato starch tablets and their diametral compression were simulated numerically and verified in a laboratory experiment to analyse the

The idea of sustainable development assumes that natural resources must be treated as limited goods and that waste must be managed rationally. This idea and the constant striving to reduce production costs make the use of waste materials as substitut

Frictional behaviour of wheat on corrugated steel walls, pressure distribution, and grain flow were investigated using a silo model with a square cross section. Corrugated steel sheets were attached to both side walls of the model silo, while clear p

The discrete element method (DEM) parameters of wheat were calibrated for the modelling of a grain storage system. In addition, the effects of material parameters on the accuracy of DEM modelling of the oedometric compaction and unloading of bulk whe

A study was conducted to simulate numerically the effects of internal inserts in the form of an annular segment attached to the wall of a cylindrical container. A series of DEM simulations were performed with an assembly of 200,000 spherical particle

A series of the DEM simulations of the outflow of wooden spheres from a flat-bottomed container was reported, considering the maximum diameter to arrest the flow. Numerical simulations of the discharge process were performed, and the micro-mechanics

Design codes do not suggest recommendations for the calculations of insert loads and silo wall loads with inserts. Numerical simulations appear to be a promising means to fill this gap. The vertical loads on inserts immersed in wheat contained in a m
