Abstract
This report summarizes the effort to develop a multiphysics modeling framework for sublimation mass
transfer processes. The aim of the project was to develop a multiphysics code capable of predicting phase
change between solid and gas in a closed container, and the movement of material within such a container
when exposed to various exterior environmental conditions. Two modeling frameworks were developed
towards this aim: one with a high-fidelity computational fluid dynamics (CFD) structure, and the other as a
fast reduced-order model. Ultimately, both attempts were unsuccessful due to instabilities in the code and
physical processes for which there is no adequate numerical representation. Both modeling attempts are
briefly detailed before providing a brief survey of recent updates in the literature, and a recommendation
for future work on this subject.
