Options🔗

The specie model represents the lowest-level thermophysical entity, responsible for:

• the specie name,
• molecular weight, \(W\) [kg/kmol],
• number of mols, \(n\) [mol], and
• gas constant \(R_g\) [J/kg/K].

Usage🔗

specie
{
    molWeight       <molecular-weight>

    // Optional; default = 1
    massFraction    <fraction>
}

Note that the gas constant is a derived quantity, calculated as:

Where \(R\) is the universal gas constant with the value 8.314 [J/K/mol]
