Abstract
The CVS flight experiments conducted aboard ISS during April 18 � 21, 2023 focus on microgravity thermal-fluid technology demonstrations related to liquid amine CO2 scrubbing aboard spacecraft. The central objectives of the work include the establishment and limits of stable passive capillary-driven �massively� parallel planar thin film flows across �Contactor� and �Degasser� as functions of flow rate, flow direction, flow resistance, heat input, viscosity gradients, condensate collection and return, fluid distribution, and interfacial stability, among others. An overview of the flight hardware including description of the components, crew procedures, flight operations, and summary of accomplishments is reported in a companion paper (Part I). This paper (Part II) highlights certain details of the tests performed, data reduction, data archive, analysis, and technology impacts. Over 49 diagnostics are recorded using a single HD video downlink during the nearly 22 hours of operations.
