Hydrodynamics in textile materials

(M.M.C.G. Warmoeskerken)

In all wet textile processes, the flow through the porous material is the key phenomenon. Despite of that little is known about flow phenomena in textiles. This project is aimed at gaining more and better knowledge of the hydrodynamics in porous textile structures. The textile material has been characterised in terms of a bi-porous medium. A theory based on a combination of Darcy flow and orifice models has been developed and validated by model experiments. This work has been resulted in a PhD-thesis. The work will be continued with emphasis on LDA and the application of numerical techniques like CFD and lattice Boltzman.
