For the simulation of the impregnation process of Resin Transfer Moulding, the permeability
of the textile is a key input parameter. Using Darcy’s law, the permeability can be derived
from a numerical simulation of the fluid flow for a unit cell problem. In this paper we present the
results of simulations with a Stokes solver, implemented in the permeability predicting software
FlowTex. The results are compared with those of a Navier-Stokes solver and validated using theoretical
results for model problems and with experimental data for real textiles.
