Predict filter efficiency, filter lifetime and dust holding capacity of a filter with the FilterDict module.

With FilterDict, you can predict the outcome of single pass or multi pass tests in various setups. Single pass tests can be performed with constant flow rate or constant pressure drop. Multi-pass tests can be performed starting from an initially clean or initially polluted test reservoir.

The fluid to be filtered can be air, water or oil, and test dusts may be SAE standard test dusts, soot, or any user defined particle size distribution. In fact, any liquid-solid separation can be simulated for as long as the concentration of dust particles is relatively low – sludges or slurries are not possible. Since the 2023 release FilterDict includes methods to simulate coalescence of liquid droplets. The coalescence models are separately licenses, so please contact filtration@math2market.de if you are interested in this feature.

FilterDict models depth and cake filtration, either in a crossflow or the usual dead-end filtration setup. Not yet included in FilterDict is the possibility to simulate filter cleaning by pulse jets or other methods.

FilterDict allows simulations on different length scales. Depending on your FilterDict license, different options are selectable.

At the Filter Media scale, simulate the filtration process on a porous media generated with GeoDict’s structure generation modules, or on models obtained from 3D-image data (µCT, FIB-SEM, etc.) imported and segmented using ImportGeo-Vol.

At the Filter Element scale, simulate the filtration process on single or multiple pleats generated with PleatGeo, on filter elements, or on DPF (Diesel Particulate Filter) structures.

At the Complete Filter scale, simulate the filtration process on a CAD model of the complete filter including the filter housing. The CAD model must be imported using ImportGeo-CAD.
