Dataset to accompany: Heat flux in low mass flux horizontal cryogenic flow

Current two-phase cryogenic heat transfer models are used to predict flow behavior of cryogenic fluids during transfer, as a heat sink, and when used in specialized heat exchange applications. To address errors in current predictions for horizontal flow at low mass flux with large tubes, this dataset presents thermodynamic data and high-speed imaging for liquid nitrogen flow in a tube of inner diameter of 34.8 mm at mass fluxes smaller than 10 kg/(m^2 ^s). A description of the test apparatus, further details on test conditions, and comparison with existing models are given in the thesis, \"Heat flux in low mass flux horizontal cryogenic flow\". Included in this dataset are a table of steady and unsteady datapoints, time traces from each test, the most relevant images from each test, and Python files to plot data.

The Laser-Aided Imager for Cryogenic Applications (LAICA) was developed at the Washington State University (WSU) Hydrogen Properties for Energy Research (HYPER) Center between 2023 and 2025 to investigate flow boiling of liquid cryogens. A detailed description of the system can be found in the conference Proceeding, \"Development of a flow boiling visualization experiment for liquid hydrogen.\"

The data generated between August 2024 and July 2025 was funded through a NASA Space Technology Graduate Research Opportunity (NSTGRO) grant number 80NSSC24K1357 and thus is publicly available here.

Enclosed here are steady state thermodynamic data points (**ReportableDataLog_LN2_Final_Cleaned.csv**), images (**Test08.zip** through **Test19_Part2.zip**), videos (**SampleVideos.zip** and in **TestXX.zip** folders), and Python files for analysis (**Python.zip**), using liquid nitrogen. Raw data points are compiled in **\"ReportableDataLog_LN2_F...,
