The pureMixture model describes a single phase mixture that can be approximated by a single component, e.g. an individual specie, approximation for air etc.

Usage🔗

The pureMixture is set in the top-level thermoType dictionary:

thermoType
{
    mixture         pureMixture;
    <...>
}

All properties must be defined in a mixture sub-dictionary taking the form:

mixture
{
    specie
    {
        <...>
    }
    equationOfState
    {
        <...>
    }
    thermodynamics
    {
        <...>
    }
    transport
    {
        <...>
    }
}

where <...> entries depend on the top-level thermoType options detailed earlier.
