Recent studies focusing on predicting the self pressurization play a significant role in the design of cryogenic storage systems since tank pressure must be controlled for long duration space missions. Incident solar radiation heats the fluid in the tank over time vaporizing the cryogenic liquid. As the liquid vaporizes, the tank pressure increases. The objective of the current research is to develop a finite volume based Computational Fluid Dynamic (CFD) model of tank pressurization in reduced gravity using an Energy of Fluid (EOF) approach. The FLUENTpressure-based computational model is significantly enhanced to include the EOF method, which will solve the energy equation in terms of internal energy. The enhanced model will numerically predict the thermodynamic properties in each computational cell. The simulation results will provide temperature and pressure histories for a given tank geometry and fill. The objectives of the current study are to complete the model development and validate the model using existing experimental data for tank pressure.
