Heat Transfer Correlations for Complete Cryogenic Pool Boiling Curve

The proposed effort concerns technologies related to cryogenic propellant production, storage, transfer, and usage to support NASArsquo;s in-situ resource utilization (ISRU) goals.nbsp;nbsp;They include a broad range of applications, scales, and environments consistent with future NASA missions to the Moon and Mars.nbsp;nbsp;More specifically, this project will address development of a piecewise-smooth set of correlations for use in lumped node codes to facilitate prediction of the entire cryogenic pool boiling curve (local wall heat flux versus wall-to-fluid temperature difference) encountered in cryogenic storage and transfer systems.nbsp;nbsp;For the Phase I study, focus will be placed on developing a model for critical heat flux (CHF) for both quenching and heating configurations, which will be validated against databases for LHe, LH2, Ar, LN2, LO2, and LCH4.nbsp;nbsp;
