Flow-induced deformation of filter media - part 2: Modeling and simulation
The majority of simulation models for filter elements assume that the filter media are "rigid bodies". In reality, it is observed that the fluid flow causes deformations which can lead to well-known (and undesired) effects like pleat collapse, pleat crowding etc. Several works were devoted to the development of models and methods to take into account this Fluid-Porous-Structure Interaction (FPSI) in order to obtain more realistic simulation results. This is accomplished by suitable coupling of Computational Fluid Dynamics (CFD) with Computational Structural Mechanics (CSM).
