| Abstract: | In order to deeply study the motion law of the airflow in the inertia deposition-separation chamber of 4TZL1800 combine harvester threshing prior to cutting,a physical model of inertia deposition-separation chamber was developed by the combined with reynolds-averaged N-S equations of fluid mechanics.The airflow characteristics in the inertia deposition-separation chamber of different backwall inclinations,including the velocity vector diagram,the pressure distribution chart,and the changes of the pressure a... |
