Investigation of air filtration efficiency for nanofiber based filters in ultrafine particle size range
Original language description
In this work, 3D filtration modeling utilizing realistic SEM image based 3D structure model, transition/free molecular flow regime, Brownian diffusion, particle-fiber interactions, aerodynamic slip and sieve has been proposed and used for different polyurethane nanofiber based filters. For the model validation purposes, two polyurethane nanofiber layers prepared by the electrospinning process (having identical average fiber diameter, 120nm, but different average pore size) were combined to form 2 pairsof nanofiber based filters; each pair consist of two filters having comparable mass area and thickness. Filtration efficiency characteristics of prepared filters were determined experimentally in the ultrafine particle size range (20-400 nm). It has beenfound that the proposed model is able to reasonably predict the measured filtration efficiency curves for all tested filter samples.
