Based on the CFD technology's negative pressure chamber air flow field simulation analysis of the aspiration drum precision seeding mechanism

摘要

Through using the ICEM CFD software, we make a model and mesh division to one of the aspiration drum precision seeding mechanism's negative pressure chamber. And we reuse software ANSYS FLUENT to make simulation analysis of the negative pressure chamber for flow field. The conclusion reflects the distributor in the suction of air distribution in the process of the situation correctly. That provides references for distributor structure optimization design, and provides the guidance for experiment so as to save manpower, material resources and the time.
