gasusually
Gasusually is a term used in some discussions of gas-phase modeling to describe a simplifying heuristic in which a multi-component gas mixture is treated as if its transport and thermodynamic properties are governed primarily by the largest constituent. The term is not part of standard thermodynamics and is not widely adopted in peer-reviewed literature.
Origin: The term is a modern informal neologism, sometimes found in notes and informal discussions in the
In practice, gasusually would imply using property correlations or transport coefficients derived from the dominant species,
Limitations include potential inaccuracies for reactive or strongly interacting mixtures, where trace components participate in key
