Analysis of Airflow Field of Toss Device of Yellow Corn Forage Harvester
Abstract : Use a very important tool called ICEM CFD integrated in ANSYS
Workbench to mesh the model of toss device and then apply the software
FLUENT to simulate numerically and analyze the velocity distribution and
pressure distribution, based on the RNG k-epsilon model. Numerical
simulation results showed that air flow field and pressure distribution
of toss device were asymmetry. Maximum wind speed of fan exit was 42.8
m/s, which met the actual needs. In a word, the design of toss device
was reasonable. But there was the existence of the secondary flow in
toss cylinder, making some gas couldn’t flow smoothly, thus
affecting delivery efficiency. Through analysis of the stress field in
the blower, the results showed that static pressure of windward side
blade increased from roots to ends and flow channels between fan blades
in different positions showed different static pressure characteristics.
The maximum static pressure of windward side blade was 878 pa, the
minimum static pressure of lee side blade just passing the export of fan
was -950 pa, the negative pressure meaning suction. The conclusions
provided a reference for structural optimization and performance
improvement of the toss device of Yellow Corn Forage Harvester.
