LATTICE BOLTZMANN METHOD: A MESOSCOPIC APPROACH FOR THE PERMEABILITY PREDICTION IN COMPLEX GEOMETRIES

摘要：

The present work studies the pore-level fluid flow in three-dimensional multifilament woven fabrics. Lattice Boltzmann method is employed to simulate the fluid flow in pores of the reconstructed fabrics. The geometry used for the three-dimensional simulations resembles bi-axial, plain woven fabrics. Such fabrics are characterized by two distinct porosities: yarn porosity (porosity of a single multifilament yarn), and weave porosity (porosity of the fabric, if the yarns are assumed to be solid). The full permeability tensor of such fabrics, including cross-plane and in-plane permeabilities, is obtained by imposing a pressure gradient in three directions.
