The bounce-off effect on the initial collection efficiency of Brownian aerosols in fibrous filtration.

By using the Brownian dynamics simulation method, the bounce-off effect of aerosol particles on their initial collection efficiencies in fibrous filtration is investigated in the present work. Based on the simulation results and available aerosol filtration experimental data, two new correlations for predicting the initial collection efficiency are derived. It is found that the correlations developed in this work provide accurate agreement with available experimental results.
