NASA selects proposals to conduct fluid physics experiments on the boiling International Space Station in support of the Tr cryogenic propellant tank

NASA’s Physical Science Research Program has selected two flight proposals in response to the research announcement “Physical Science Research Opportunities, Appendix A: Solicitation of Proposals for Fluid Physics Experiments on the International Space Station boiling in flux to support cryogenic propellant tank transfer research”.

Researchers will conduct experiments on the International Space Station (ISS) to determine the best use of the new flux boiling module for flux boiling and condensation experiment (FBCE) in support of research on the transfer of cryogenic propellant tanks into space. The research from the selected proposals plans to develop a fundamental understanding of cooling, the process of cooling the transfer line between cryogenic propellant tanks, using a combination of high-fidelity experimental techniques and computer simulations. Cooling is of paramount importance during cryogenic liquid transport and involves complex hydrodynamic and thermal interactions between liquid, vapor and channel wall. The data and modeling from these investigations will improve the knowledge base for the development of new cryogenic propellant tank transfer systems. These technologies are a key part of NASA’s future space exploration plans.

The physical science research program is managed by the Biological and Physical Sciences Division director of NASA’s science missions. This program conducts research in the basic and applied physical sciences, with the goal of advancing scientific discovery, enabling space exploration, and providing benefits on Earth. The program advances fundamental research by studying the fundamental laws of the universe and physical phenomena in the absence of gravity. The program also conducts applied research, which contributes to the basic understanding of space exploration technologies that will aid our return to the Moon and our journey to Mars and beyond. Both have led to improved space systems or new products on Earth.
