Evidence proximity, not a safety rating. This page describes what was tested and where each value comes from.
ACME E-FIELD Flames has no individual runs to place.
0 of 0 runs drawn.
As written in the PSI record:
The objective of this investigation is to better understand the relationship between electric field voltage and chemi-ion current, analyze the dynamic response of flames to electric field changes, evaluate soot formation, and characterize stabilized near-limit lifted flames.
PSI has summary rows only for this investigation (32 rows in PSI-22_Experimental table_ACME E-FIELD Flames.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.

| Row | Test Type | Test Day | Year | Month | Date | Mesh Polarity | Fuel Bottle | Fuel Conc | Flames Ignited | Notes |
|---|---|---|---|---|---|---|---|---|---|---|
| 1 | First round of tests with coflow burner | 18073 | 2018 | 3 | 14 | negative | 100% CH4 | 100% | 10 | Test day is formatted YYDDD where YY identifies year and DDD identifies day of year (GMT). |
| 2 | First round of tests with coflow burner | 18078 | 2018 | 3 | 19 | negative | 100% CH4 | 70% | 10 | Mesh polarity refers to the polarity of the high-voltage power supply and the copper electrode relative to the burner. |
| 3 | 100% | Fuel Conc. (diluted with nitrogen on a volume basis) was varied between tests, but typically matched the bottle. The list only accounts for flames ignited. | ||||||||
| 4 | First round of tests with coflow burner | 18080 | 2018 | 3 | 21 | negative | 40% CH4 | 40% | 8 | Flames Ignited is the number ignited on that day (neglecting the day change on ISS). |
