As written in the PSI record:
Objective: The objective of this investigation is to better understand the structure and stability of laminar diffusion flames in microgravity. Specific objectives of this investigation were: 1. To investigate the structure of laminar diffusion flames in microgravity to understand the stabilizing mechanisms at the flames base. 2. Determine the liftoff velocity limits for different fuels and burner diameters. 3. Evaluate the impact of fuel dilution with nitrogen on soot formation and flame stability. 4. Quantify the effects of microgravity on flame length and radiative heat loss compared to normal gravity conditions. 5. Validate numerical models for flame dynamics, soot production, and thermal radiation in non-premixed flames.
PSI has summary rows only for this investigation (12 rows in PSI-106_Experimental table_Slice.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.
