Application of coupled CFD-DEM simulation to separation process in combine harvester cleaning devices

Mehr zum Buch

The book explores the coupled CFD-DEM approach for simulating grain separation in combine harvester cleaning devices. It outlines key influencing factors and provides a database for particle parameterization. The separation process is analyzed in two phases: first, through a numerical simulation in a vertically oscillating box with airflow, assessing how various parameters affect separation time and grain purity. The second phase involves testing a segment of the cleaning device, comparing numerical results with experimental data to validate the method's effectiveness.
