Macroscale Simulation of N95 Respirators

This talk presents a detailed analysis of the instantaneous collection efficiency and pressure drop of an N95 respirator under particle loading. The simulations are conducted for when the mask was tested in a setting like that proposed by NIOSH. We considered particles with the size and charge distributions similar to those of the particles used by common filter testers (e.g., TSI 8130). Our numerical predictions were compared with the experimental data reported by Balazy et al. (2006) for the initial (clean) efficiency of N95 masks, and good agreement was observed. The simulation platform developed in this study can be used in design and development of future facemasks and respirators.
