MS 2.26: Modeling, simulation and validation of filtration problems

Oral 20 Minutes

The goal of this study is to optimize a dual-fiber filter media by increasing the dust holding capacity (DHC), while maintaining the initial pressure drop and initial filter efficiency. Three main parameters define the performance of a filter, namely the DHC, filter efficiency and pressure drop. The DHC defines the quantity of solid particles which a filter media can trap and hold before the...

MS 2.26: Modeling, simulation and validation of filtration problems

Oral 20 Minutes

Reverse Osmosis Membrane (ROM) filtration systems are widely utilized in waste-water recovery, seawater desalination, landfill water treatment, etc. During filtration, the system performance is dramatically affected by membrane fouling which causes a significant decrease in permeate flux as well as an increase in the energy input required to operate the system. Design and optimization of ROM...

869. Comparative simulation of reactive flow in catalytic filter using 3D pore-scale model on CT image and 1D effective model

MS 2.26: Modeling, simulation and validation of filtration problems

Oral 20 Minutes

In order to improve the performance of the exhaust after treatment system and keep reasonable complexity, the number of the used devices is reduced by enhancing wall flow particulate filters with a catalytic functionality, like selective catalytic reduction in diesel or three way catalysis in gasoline vehicles. In this case the solid matrix of the filtering media consists from inert grains and...

752. Influence of the microstructure of non-woven media on filtration performance at different operational regimes.

MS 2.26: Modeling, simulation and validation of filtration problems

Oral 20 Minutes

In this work, we study the efficiency of the filter media at different operational regimes. In particular, we focus on how the media microstructure influences the efficiency performance, which is quantified by macroscopic parameters. We investigate the microscale characteristics since the filtration is an intrinsically multiscale process. On one hand, contaminant adsorption onto the fibre...
