Abstract
Equations for predicting the minimum efficiency and most penetrating particle size for fibrous filters have been derived by considering the diffusion and interception mechanisms. The results show that the most penetrating particle size decreases with increasing filtration velocity and with increasing fiber volume fraction, and increases with increasing filter fiber size. The corresponding equation for minimum efficiency has also been derived showing the dependence on filtration velocity, fiber volume fraction, and fiber size. These results have been compared with experimental data and satisfactory agreement has been obtained.This publication has 4 references indexed in Scilit:
