The effects of woven structures on fluid now through basic weaves of m
onofilament filter cloths are studied numerically using the fluid-flow
software FLUENT. The now pattern and resistance to flow in the inters
tices are obtained as results of the numerical solution. The results s
how that the construction of the fabric pores has a significant influe
nce on now pattern in the interstices and downstream. Plain weave give
s the highest fluid now resistance, while satin weave has the lowest w
ith the same thread count.
