Evidence proximity, not a safety rating. This page describes what was tested and where each value comes from.
Where SAME’s runs sit in condition space, in the Atlas chart window. Other investigations’ runs in this regime are dimmed.
0 of 8 runs drawn · 8 runs without O₂ or pressure are not drawn.
As written in the PSI record:
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.
Computed from the 8 run rows below: what varied, what was held constant, and what was never recorded.
| Axis | State | Range | Basis | Recorded |
|---|---|---|---|---|
| O₂ | not recorded | no o₂ column in the PSI table | not recorded | 0/8 |
| Pressure | not recorded | no pressure column in the PSI table | not recorded | 0/8 |
| Flow | varied | 5.0–10.0 cm/s · 2 levels | measured | 4/8 |
Nothing from this investigation can be placed on an O₂ × pressure chart: 8 runs: no O₂ value recorded in the source row.
Normalized values with the original cell beneath each. Inspect a row for its conversions, flags, source and distance to your scenario.
