Pleated filters are a widely used and intensively studied design concept in filtration. Even in situations of confined construction spaces and other constraints, many degrees of freedom remain for the design such as the length, the geometric shaping and the packing density (or width of) of the filter pleats.
A purely experimental approach for the identification of an optimal design for a given application can become very timeconsuming and costly. In order to accelerate the process, we develop models and simulation methods for the computer-aided optimization of filter pleats.
Clean Flow Regime
For the identification of the pleat design with smallest initial differential pressure, both analytical methods and CFD (Computational Fluid Dynamics) are available. The approach based on computer simulations offers the additional feature to find the pleat shape with small initial differential pressure drop and highest degree of uniformity of the fluid flow at the media surface.
