11.1.7. Gas Phase¶
11.1.7.1. RO_G0¶
Data Type: DOUBLE PRECISION
Specified constant gas density [kg/m^3 in SI]. An equation of state, the ideal gas law by default, is used to calculate the gas density if this parameter is undefined. The value may be set to zero to make the drag zero and to simulate granular flow in a vacuum. For this case, users may turn off solving for gas momentum equations to accelerate convergence.
11.1.7.6. MW_AVG¶
Data Type: DOUBLE PRECISION
Average molecular weight of gas [kg/kmol in SI]. Used in calculating the gas density for non-reacting flows when the gas composition is not defined.
11.1.7.7. MW_G(SPECIES)¶
Data Type: DOUBLE PRECISION
\(1 \le Species \le 100\)
Molecular weight of gas species [kg/kmol in SI].
11.1.7.9. SPECIES_G(SPECIES)¶
Data Type: CHARACTER
\(1 \le Species \le 100\)
Name of gas phase species as it appears in the materials database.
11.1.7.10. SPECIES_ALIAS_G(SPECIES)¶
Data Type: CHARACTER
\(1 \le Species \le 100\)
User defined name for gas phase species. Aliases are used in specifying chemical equations and must be unique.
