Investigating the Effects of Inhomogenous Porosity on Resin Infusion
During a resin infusing process a polystyrene foam is located between an immovable flat lower surface and an initially flat vacuum bag on top. After infusion the top surface becomes distorted. It is expected that variations in the porosity cause the foam to expand or contract unevenly during the infusion process. As resin is injected into the foam it will flow according to the Darcy-Brinkmann equation for porous media. The resulting pressure field can expand or contract the pores, thus changing the overall shape of the foam. We wish to validate this theory by using the Deal.ii finite element library to approximate the solution of a system of partial differential equations over a sequence of computational domains.
