A numerical analysis of pressure drop and particle capture efficiency by rectangular fibers using LB-DE methods

Abstract: In this work, a coupled lattice Boltzmann method (LBM) and discrete element method (DEM) are used to simulate the particle transport and deposition on rectangular fibers of clean filter. The LBM is employed to describe the fluid flow around the fibers, whereas the DEM is used to deal with the particle dynamics. The effects of the Reynolds number, the fiber aspect ratio and the arrangement of fibers (i.e., orientation angle of a fiber) on the pressure drop and capture efficiency are investigated at the initial … Show more

“…Micro-nano fiber nonwovens are composed of fibers whose filtration performance is affected by multiple factors; among them, the fiber orientation is an important one affecting the filtration performance of nonwovens. [20][21][22] In addition, the fiber distribution determines the mechanical anisotropy of nonwovens, thus affecting various properties of nonwovens. Therefore, it is of great significance to study the influence of fiber arrangement or orientation distribution on the filtration performance of micro-nano fiber nonwovens.…”
