摘要
建立了异极性荷电颗粒在交变电场中的团聚系数模型,将其应用到Sectional算法中,模拟电场团聚作用对超细颗粒的脱除效果。比较模拟结果与文献中实验数据后发现,在初始浓度不太高时,模拟结果能较好地与实验结果相吻合,而在初始浓度很高时,两者有较大的差异。文中对造成上述现象的可能原因进行了分析．
Coagulation coefficient of bipolar charged ultra-fine particles in AC field was modeled, which was applied to Sectional algorithm to simulate the removal efficiency of the ultra-fine particles. The simulations were compared with the experimental data in the literatures. It was found that the simulations were consistent with the experimental data at lower initial particle concentration while considerably different at higher initial particle concentration. The probable reasons were analyzed in the article.
