Nonwoven filter media are increasingly popular for their filtration efficiency for both liquids and gases. The applications include automobile, petrochemicals, pharmaceuticals and food processing industries, as well as clean room technologies. Nonwoven filters are also in use for dust filtration in mines, metal foundries, aluminum smelters, electric arc furnaces, basic oxygen furnaces, incinerators, and for diverse industrial ventilation systems. Using CFD to simulate the flow inside a filter, a design can be analyzed and parametric modeling can derive suitable design modification ideas. It is also possible to analyze the filter performance after prolonged usage when the accumulated dust and dirt enhances flow resistance.
