Objective
One of the major goals of this investigation was to quantify the sizes that the liquid smoke particulate achieves in low gravity and to relate the droplet size distribution to the smoke generation and smoke transport conditions in the experiment. A numerical code was to be developed to predict the smoke droplet growth as a function of the fuel pyrolysis rate, the thermodynamic properties of the pyrolysis vapor, and the flow environment.
SAME (PSI-102, Comparitive Soot Diagnostic Hardware, International Space Station (ISS)). 8 test runs from NASA PSI (DOI 10.60555/gd4k-8h62).

Representative Conditions
Median of the values reported across this investigation's test runs.
- Fuel / Material
- Teflon, Kapton, Silicone, Lampwick: same conditions as 1-4, Dibutyl Phthalate: same conditions as 1-4
- Gravity
- 0 g (microgravity, ISS / Cygnus flight)
- Airflow-Equivalent Gravity
- 4 of 8 runs, ~zero g (3), ~between g (1)
- Oxygen Concentration
- Not reported
- Ambient Pressure
- Not reported
- Airflow Velocity
- 0.05 m/s
The PSI record mentions both flight and ground work; 0 g reflects its ISS / Cygnus flight metadata.
Findings summary
8 test runs recorded; 5.0–10.0 cm/s (n=4); microgravity (0 g, ISS / Cygnus flight); 4 runs have airflow comparable to partial-gravity buoyancy.
