Abstract:

For the accurate simulation of Liquid Composite Moulding processes, the input of the permeability of the preform is required. The permeability of a textile can be obtained experimentally, or can be computed. To compute the permeability, the software FlowTex was developed at the KU Leuven, as part of the textile modelling software package WiseTex. FlowTex transforms the vector description of the textile models into a voxel description, which is input for the finite difference flow solver. In this paper we present the implementation of the flooding algorithm to make this transformation more efficient. Validation and convergence studies, both for the voxelisation as for the permeability computation are presented.
