abstract = {The water flow rates of commercial sterilizing grade 10″
filter cartridges were simulated by Computational Fluid
Dynamics (CFD) and compared to experimental data. This study
compares four methods used to reconstruct the internal pleat
geometry ranging from generic designs to analysis of
microscopic images. The impact of the cartridges’ plastic
cage on flow resistance was studied and found to be
negligible. A systematic overestimation of the simulated
filter flow rate was attributed to additional hydrodynamic
resistance of the non-woven material between the pleats. The
permeability of the non-woven material was estimated by
fitting CFD models to experimentally determined water flow
rates and compared to the permeability of this material as
directly measured with a flow cell. Good correlation between
CFD-based estimations and directly measured values was found
at low pressures, while differences at high pressures
indicated the existence of further flow resistance, which is
hypothesized to be caused by deformation of the pleat
geometry under pressure.},
