Carbon fibre composites materials have been significantly developed in aeronautics due to their excellent specific properties. Their manufacturing manufacturing process through Liquid Molding can be modelled by a two-phase transient flow in a porous medium. The modelling of such flows has led to the development of efficient but very costly solvers especially for large and complex 3D parts encountered in aeronautics. Thus, a reduction of the transient problem by the Proper Orthogonal Decomposition combined with a Galerkin projection (POD-Galerkin) is studied. The originality of the proposed approach is to use a well-chosen database of steady state flows, fast to simulate, in order to solve cost-effectively a transient problem in complex geometries.
