The primary objective of this project is to better understand gas diffusion through natural cork structures by comparing simulations of gas diffusion through natural cork to experimental measurements of oxygen gas diffusion through the same structure. The cork's internal structure is measured using x-ray computed tomography (CT). From the measured internal structure, a simple mapping is assumed converting the measured x-ray computed tomography images into a 3D map of local diffusion coefficient. Specifically, it is assured that the x-ray CT pixel value is inversely proportional to the diffusion coefficient of oxygen through the cork. A diffusion model for the cork structure was developed using finite commercial finite element method simulation software and the necessary boundary conditions. The primary intention is to create model which can help in understanding the ingress of oxygen through cork. By comparing simulation and experimental results, the role of the cork's internal structure in gas diffusion can be better understood.
