Modelling of the drag force of agricultural seeds applied to the discrete element method
Original language description
Improvements in design and performance of post-harvesting equipment, such as graindryers, cleaning machines, silos, bucket elevators and conveyors, depend on betterknowledge of the physical properties and dynamic behaviour of seeds. In this work,experimental data regarding form, size, orientation, and terminal velocity of seeds of soya,oat and maize were obtained using image processing and fluidised bed methods. Thediscrete element method (DEM) has been applied for the simulation of different processesinvolving agricultural seeds, but aerodynamic properties, such as drag force, are not alwayscorrectly considered. In this work, a clump-based drag engine model for the Yade DEMsimulation tool was developed, and DEM simulations of the seeds free fall were performed.The comparison between the simulation results and the experimental data shows that thedeveloped method is accurate, with its accuracy dependent on how well the modelled seedgeometry can be approximated by an ellipsoid.
