چکیده
Introduction Computational fluid dynamics (CFD) has been used to simulate the flow during vacuum infusion [12], sheet moulding compound (SMC) [3-4], the auto-clave process [5] and twin-screw extrusion. Three-dimensional geometries were studied and porous media and multiphase flows were treated with a homogenous approach. The advantages and drawbacks of such a methodology are here discussed based on previous work [1-5] and some new results on twin-screw extrusion. To exemplify: For the vacuum infusion process the porous media can be located in a complex mould with moving boundaries and can have an anisotropic, spatial and time dependent permeability. The pressure within the mould during compression moulding of SMC can be predicted if shear-thinning effects are accounted for.
