2D-Simulation of depth filtration in pleated filter
Résumé
Pleated filters are widely used for many industrial applications in air treatments due to their high effective surface area for a low overall dimension. Experimentally, Del Fabbro et al. (2002) observed that pleated filter pressure drop evolution with solid particles could be described by 3 periods. Among these is a period of depth filtration when particles are mostly collected within the fibrous medium. The aim of the work described in this paper is to characterize the filtration step numerically using the GeoDict code. We present general ideas how the depth filtration is taken into account and results on a specific pleat case.
