As written in the PSI record:
By using the Flame Extinguishment (FLEX) experimental data from the Physical Sciences Informatics (PSI) system of combustion science, the purpose of this grant was to conduct new simulations and ground-based experiments using ozone-sensitized counterflow flames to: 1) Develop a new diagram of the flammability limits of diffusional cool flames affected by radiation, diffusion, and convection. 2) Bridge the knowledge gap between the flammability limits and extinction limits of hot flames and cool flames. 3) Verify the phenomena observed on the ISS flame extinguishment experiments. 4) Obtain new, quantitative data of extinction limit, flame temperature, and species distribution for the validation of kinetic and radiation models involving cool flames. 5) Extend the cool flame experiments from the original ISS droplet experiments to a more general ground-based combustion system involving radiation, diffusion, convection, and low-temperature chemistry while maintaining a one-dimensional geometry.
PSI has summary rows only for this investigation (8 rows in PSI-142_Experimental table_Data Summary Table.csv), not individual runs, so there is nothing to fingerprint run by run. The summary rows are listed below.
Nothing from this investigation can be placed on an O₂ × pressure chart: there are no individual runs to place.
PSI has no run-level table for this investigation: its experimental table holds summary rows only (each summarises a test series, not a single run), so nothing is placed or compared. The summary rows are listed below.
