20: Fluid Composition and Properties
| Command | Purpose |
|---|---|
| add_water | Compute the mole fractions of a composition variable to include ambient water vapor pressure. The computation is done on a continuous basis. |
| gas_prop | Compute gas properties on a continuous basis. |
| init_composition | Initialize gas composition. |
| init_emission | Read a spec file to determine which streams are in use at a test cell. |
| init_properties | Initialize Gas Properties. |
| set_composition |
Continuously update a composition variable based on the concentrations defined in a set of real variables. |
| update_composition | Write out gas composition. |
