prometheus.thermo_data.parsers.cea

Parser for NASA CEA thermo.inp (NASA TP-2001-210959 format).

Produces the nasa9.json schema, identical to burcat.Burcat9Parser output. The three-line interval format is shared with the Burcat9 parser via _common.parse_nasa9_interval() — the only differences from burcat9.thr are file-level framing:

  • A thermo keyword and global T-bounds line precede the species data.

  • Comment lines start with !.

  • The species section ends at END PRODUCTS.

Only the PRODUCTS section is parsed; the REACTANTS section contains fuel/oxidiser entries with no polynomial data.

Raw source file: cea_thermo.inp

Classes

CEAParser()

Parse a CEA thermo.inp file into nasa9.json schema.
class prometheus_equilibrium.thermo_data.parsers.cea.CEAParser

Bases: NASA9Parser

Parse a CEA thermo.inp file into nasa9.json schema.

Per-species structure (identical field layout to Burcat9):

  • Line 1 — species name (cols 0–17), rest is reference/comment

  • Line 2 — descriptor: n_intervals, elements, condensed flag (parsed by _common.parse_nasa9_descriptor())

  • Per interval — 3 lines parsed by _common.parse_nasa9_interval()

parse(path: str, source: str = '') → Dict[str, dict]

Parse path and return a dict keyed by canonical species ID.

Parameters:

  • path – Path to the CEA thermo.inp file.

  • source – Human-readable label for this data source (e.g. "CEA-NRL2002"). Stored in each record under the "source" key.
