Air Filtration Modelling Through Polymeric Nanofiber Based Filters

Popis výsledku v původním jazyce

In this work, air filtration process through polyurethane nanofiber based filters has been modeled in order to determine their quality factor. For this purpose, realistic SEM image based 3D structure model, transition/free molecular flow regime, Browniandiffusion, particlefiber interactions, aerodynamic slip, sieve and pressure drop calculation has been utilized. For the model validation purposes, two polyurethane nanofiber layers prepared by electrospinning process (having identical average fiber diameter mass area and thickness but different average pore size) have been used. Filtration efficiency characteristics of prepared filters were determined experimentally in the ultrafine particle size range (20-400 nm) as well the pressure drop over this filters was measured. It has been found that the proposed model is able to reasonably predict the quality factor for both analyzed filters.
