Hydrodynamic modelling of pleated cartridge filters
Year: 2004
Type: dissertation
Abstract: The primary aim of this study is to develop and validate a hydrodynamic model for the\ndesign of pleated cartridge filters. This software package is intended to develop into a\ncost effective, robust and reliable design tool to enable engineers to appraise the\noperation of a filter. Mathematical theories are still being developed in order to build\nsound software for coupled flows in geometrically complicated domains. This is mainly\ndue to the little understanding of the mathematical theories in addressing interfacial\nconstraints in coupled flows.\nA 2-D computer code has been developed to simulate both Newtonian and non-Newtonian flows in the filter. The model is based on a flow model described by the\nStokes, Continuity and Darcy equations. These equations are solved by the weighted\nresiduals finite element method. Two U–V–P schemes based on the Lagrange and Taylor–Hood elements are developed and tested on various coupled flow physical problems with\nthe latter scheme proving to be capable of coping with complex geometries. The\nlimitations of the Lagrange scheme are described. [Continues.]
