Detailed Description

template<class EquationOfState>
class Foam::hConstThermo< EquationOfState >

Enthalpy based thermodynamics package using a constant heat capacity at constant pressure.

The sensible enthalpy is evaluated as: 

    hs = Cp*(T - Tref) + hsRef
Usage
Property Description
Cp Constant Heat capacity at constant pressure [J/kg/K]
Tref Reference temperature [K] (defaults to Tstd)
hsRef Reference sensible enthalpy [J/kg] (defaults to 0)
hf Heat of formation [J/kg]

Example specification of hConstThermo for air: 

    thermodynamics
    {
        Cp          1007;
        hf          0;
    }
