Detailed Description

template<class EquationOfState>
class Foam::eConstThermo< EquationOfState >

Internal energy based thermodynamics package using a constant heat capacity at constant volume.

The sensible internal energy is evaluated as: 

    es = Cv*(T - Tref) + esRef
Usage
Property Description
Cv Constant Heat capacity at constant volume [J/kg/K]
Tref Reference temperature [K] (defaults to Tstd)
esRef Reference sensible internal energy [J/kg] (defaults to 0)
hf Heat of formation [J/kg]

Example specification of eConstThermo for air: 

    thermodynamics
    {
        Cv          724;
        hf          0;
    }
