Reduced Gravity Experiments to Measure Cryogenic Two-Phase Heat Transfer Coefficients for Future In-Space Transfer Systems

The Reduced Gravity Experiments to Measure Cryogenic Two-Phase Heat Transfer Coefficients for Future In-Space Transfer Systems will develop highly accurate models for the prediction of flow boiling rates. Specifically, the demonstration’s objective is to obtain the first microgravity steady state cryogenic heat transfer coefficient (HTC) data. It will also measure HTC during parabolic flight as a function of gravity level, mass flux, and other geometrical and flow parameters.Data collected will inform new steady state HTC models for microgravity that improve predictive capabilities for in-space propellant transfer systems.
