Design of Heat Pipe Test Facilities for Micro Reactor Applications

Heat pipe_v5.jpg

Heat pipe cooled micro-reactors are designed to produce thermal power of less than 20 MWt for remote installations. Based on the prototype heat pipes in various micro-reactor designs, heat pipe test facilities will be designed to investigate high-temperature two-phase flow behavior and its effects on heat pipe performance. The ultimate goal is to improve the heat pipe model specifically for the micro-reactor through conducting high-resolution measurements in constructed test facilities.

Modeling and Prediction of Cryogenic Propellant Behavior in Microgravity During Long-Term Storage

The ultimate goal of this project is to provide an integrated computational toolkit for NASA scientists to efficiently and accurately predict the long-term cryogenic propellant behavior in storage tanks for space mission planning. The toolkit will leverage capabilities of existing Computational Fluid Dynamics (CFD) and nodal codes used by NASA for cryogenic propellant analysis with new efficient coupling approaches and accurate fluid dynamics and heat transfer correlations.
