Decoupling Surface Topography from Gravitational Acceleration in Cryogenic Pool Boiling

Here, we provide the complete experimental dataset associated with the study “Decoupling Surface Topography from Gravitational Acceleration in Cryogenic Pool Boiling.” This dataset includes processed and raw measurements from both terrestrial (1-g) and reduced-gravity (µ-g) pool boiling experiments conducted using liquid nitrogen (LN₂) during parabolic flight campaigns. The data files contain: Boiling curves (heat flux vs. wall superheat) for all experimental conditionsHeat transfer coefficient (HTC) data derived from experimental measurementsUncertainty quantification for heat flux, wall superheat, and HTC based on NIST guidelinesPressure and saturation temperature measurements during experimentsSpreading correction factors obtained from ANSYS-based conjugate heat transfer simulations The dataset is organized into separate files for clarity: All boiling curves_after ANSYS.xlsx → corrected boiling curves with spreading effectsUncertainty Data_All curves.xlsx → uncertainty analysis for all datasetsLN2 Press and temp_1g experiment.xlsx → pressure and temperature data for 1-g experimentsLN2 Press and temp_ug experiments.xlsx → pressure and temperature data for µ-g experimentsSpreading Coefficient_All curves.xlsx → substrate heat spreading correction factors These data support the key findings of the study, including: Significant reduction in critical heat flux (CHF) under reduced gravityEnhancement of heat transfer coefficient (HTC) prior to CHF in µ-gDemonstration of microlayer-driven heat transfer mechanisms independent of surface roughness All data are provided in .xlsx format and are intended to ensure full reproducibility and transparency of the reported results.
