As written in the PSI record:
The objective of this ground investigation was to use flight data obtained from PSI through NASA’s Flame Extinguishment Experiment (FLEX) to quantify how externally imposed thermal and convective perturbations regulated the dynamics and ultimate fate of already established droplet cool flames, and to explain run-to-run variability by isolating the roles of deliberate heating and unintentional drift-induced convection. Focusing on both small and large droplets, the work mapped stability windows for ignition, sustained oscillation, transitions to hot ignition and warm-flame behavior, and extinction under microgravity. By leveraging and extending the FLEX data in the PSI, this study produced reusable models and sensitivity analyses that coupled low-temperature chemistry with transport and radiative effects.
PSI has no experimental table for this investigation, so no run fingerprint can be computed.
Nothing from this investigation can be placed on an O₂ × pressure chart: there are no individual runs to place.
PSI has no experimental table for this investigation (no run-level table): only the record text above.
