From results of the numerical solution, the flow pattern and the resistance to flow in the interstices were obtained. Results of this work show that the construction of the fabric pores has a significant influence on the flow pattern in the interstices and the downstream. It is also shown that the plain weave gives the highest fluid-flow resistance while the satin weave gives the lowest under the same thread count. Furthermore, in the case of tightly woven filter cloths, the flow is predominantly through the yarns of the cloth; while the flow will generally be directed around the yarns of a loosely woven cloth, especially if the yarns are twisted tightly. A comparison of fluid flow through multifilament woven filter cloth with that of monofilament woven filter cloth is also discussed. |
