Discrete element model calibration for industrial raw material simulations

The use of computational fluid dynamics in continuous operation industries have become more prominent recent times. Proposed system improvements through geometric changes or control strategies can be evaluated within a relatively shorter timeframe. Applications for discrete element methods (DEMs) real life simulations, however, require validated material-calibration-methods. In this paper, the V-model methodology combination with direct and bulk calibration approaches were followed to determine material model parameters, simulate occurrences. For approach test rig containment hopper, deflection plate settling zone was used. Screened drains from interacts plate, then settles at angle repose. A high-speed camera captured interaction rig, where footage used during simulation validation. measuring particle size, shape density, while confirming friction restitution coefficients determined method. repeated various geometrical changes. Three categories validation established, namely speed assessment, -trajectory assessment -plate assessment. conclusion, significant calibrating required parameters.
