In this study, a 2-D model has been built using COMSOL Multiphysics® to analyze a triple coupled physics problem involving simultaneous gas diffusion, heat transfer, and structural mechanics in a pipe due to the flow of high-pressure carbon dioxide. The problem geometry and boundary conditions were based on the analysis by Rambert et al. who have published the most advanced modeling work in the open literature. Comparison of results with the Rambert group’s work showed excellent agreement. It will be demonstrated that COMSOL Multiphysics® software offers a more efficient and user friendly capability for solving complex multiphysics problems.
