Abstract

This work describes the development of a Finite Element Model (FEM) for use in determining adsorption system performance. The considered interactions are between Zeolite 13X and water vapor for the purposes of engineering adsorbent characteristics and harvester device characteristics. Four objectives are evaluated in the development of a predictive model. First, to understand the implementation of adsorption systems equations and the assumptions that could prevent reliable predictability. Second, to assemble, reduce, and analyze model constants and approximations that express FEM coefficient calculations. Third, to analyze factor sensitivity of model inputs by way of a 2k factorial screening to determine which inputs would benefit from future model development. Fourth, to identify potential avenues of research that would result in novel intellectual property. The main findings of the solver factor screening indicate that micro-dispersion factors and intra-crystalline gas diffusivity are the highest value characteristics in relation to water uptake.

Acknowledgments

Without exception my time as an undergraduate Chemical Engineering student and as a Masters student at UTC has been marked by interactions with Faculty and Staff of the highest caliber. In many instances I have witnessed portraits of brilliance, service, and mercy beyond what would be normally expected. This subject matter has required a grinding effort with repeated reassessment of what is needed to achieve its completion. Dr. Sungwoo Yang has never failed to support the effort, encourage proper direction, and care for me as a person. His humility, energy, and focus allowed me to achieve results that seemed far out of reach.
