Abstract
A simulation model is presented for predicting the dust load distributions in fibrous mat and granular bed filters. The calculations are based on the interception model proposed in the previous papers.
The increment of a single-fiber or single-sphere collection efficiency due to dust loads is derived on the assumption that the interception caused by captured particles works to increase the collection efficiency as the predominant mechanism.
It is confirmed that the simulation results are similar to the experimental results qualitatively. Quantitatively, however, the effect of re-entrainment of captured particles seems to cause some difference, which is confirmed experimentally to be dependent on the inlet dust loads and the filtration velocity.
