Permeability of textile reinforcements: Simulation, influence of shear and validation
نویسندگان
چکیده
The permeability of textile reinforcements is a crucial input for the simulation of the impregnation stage of a composite material fabrication process. In this paper, we present a fast and accurate simulation method for the permeability of a textile reinforcement, based on a finite difference discretisation of the Stokes equations. Results for single layer, multi-layer and sheared models are discussed. The influence of intra-yarn flow and periodic or wall boundary conditions are considered. We compare the numerically computed permeability values with experimental data. 2008 Elsevier Ltd. All rights reserved.

متن کاملFinite difference computation of the permeability of textile reinforcements with a fast Stokes solver and new validation examples
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 res...
متن کاملPredicting the Permeability of Textile Reinforcements via a Hybrid Navier- Stokes/brinkman Solver
Numerical computation of textile permeability is important for composite manufacturing. Using Darcy’s law, permeability can be derived from a simulation of the fluid flow, i.e. after solving the Stokes, Navier-Stokes or Brinkman equations. The latter allow to model intra-yarn flow in case of permeable yarns. In this paper we present a numerical method for the calculation of the permeability of ...
متن کاملHomogenization and Numerical Simulation of Flow in Geometries with Textile Microstructures
The simulation of the Liquid Composite Moulding process is an important step for the manufacturing of composites with textile reinforcements. However, its fast direct numerical simulation is impossible on the microscale due to computational complexity reasons. We have to resort to the macroscale instead. Here, an essential task is the fast and accurate prediction of the permeability of textile ...
