Summary

The communication presents some results related to a study carried out at the Institut de Protection et de Sûreté Nucléaire (IPSN), in collaboration with company FILTRAUTO. This study deals with the modelling of the airflow in pleated filters of nuclear (High Efficiency Particulate Air Filter) and car types, and their clogging by solid particles. Indeed, the dynamic filtration of particles, i.e. the deposit of particles on a pleated filter medium, involves the variations of the filter efficiency and pressure drop. Our study aims at acquiring experimental results and at developing associated modelling on the modifications of the pressure drop versus the mass of particles deposited; this passes by the knowledge of the airflow within the filter pleats.
