Computation of Permeability of Textile with Experimental Validation for Monofilament and Non Crimp Fabrics

For the manufacturing of composite materials with textile reinforcement, the permeability of the textile is a key characteristic. Using the law of Darcy, permeability can be derived from a numerical simulation of the fluid flow, i.e. by solving the Navier-Stokes or Brinkman equations. In this paper we present the results of simulations with two different flow solvers: a finite difference NavierStokes/Brinkman solver and a lattice Boltzmann solver. The results are validated with theory and experimental data.
