摘要(Abstract):

用SIMPLE算法编制的程序通过对离心风机在不同工况时流场的数值模拟 ,分析了在不同负荷时流场在叶片非工作面上及附近区域的情况 ,从而得出了离心风机负荷对积灰的影响
Numerical simulations of the flow field of the centrifugal fan are completed in the different load by the SIMPLE algorithm general program, and the flow fields in and near the non working surface of the blades in the different loads are analyzed. As a result, the conclusion that the loads of the centrifugal fan affect the dust deposit of the blades is gained.
