Simulation of liquid composite molding processes using a generic mixed FE-SPH method
Résumé
Composite manufacturing processes involve multi-scale phenomena. Equations governing mechanics, heat transfer and fluid flow dynamics can be derived in the scale of the problem to solve. This article focuses on addressing fluid flow simulation needs for Liquid Composite Molding processes using a generic mixed FE-SPH method. The SPH method is Lagrangian and models fluids as particles. The method has been proven to be suitable to simulate fluid flows. Special solutions have been developed for flow through porous media and non-Newtonian fluid flow. Numerical schemes for such solutions are also given. The implementation of the SPH algorithm within a structural finite element software facilitates simulation of fluid-structure for LCM processes. Several applications are presented and discussed.
