Determination of Pressure Drop and Filtration Efficiency of Filled Nanofiber Based Filters by using 3D Filtration Model

Popis výsledku v původním jazyce

In this work, two different boundary conditions dealing with the filter cake formation due to particleparticle interaction (fully sticking and slip conditions) has been tested in a theoretical study. Filtration efficiency and pressure drop are evaluatedutilizing realistic SEM image based 3D structure model, transition/free molecular flow regime, Brownian diffusion, particle-fiber interactions, aerodynamic slip and sieve. It has been found that the filtration efficiency of the fully sticking condition is higher than when particle slip was allowed. The pressure drop shows the opposite trends. Additionally, visualisations of the cake formation were created and has revealed that the cake is double in size and less dense in case of full sticking conditions.
