Simulation of Melt Blown Web and the Effect of Its Pore Size Distribution on filtration Performance

摘要

In this paper melt blown webs with different fiber dis- tributing density were simulated by the computer, and then their pore size distribution was calculated with the image analysis. Based on simulated fiber webs, the effect of 10/100 big pores on the filtration properties was ana- lyzed theoretically. It is found that the pore radius be- comes smaller and its distribution becomes more uniform with increasing line density, i.e., the fiber distributing density.
