Detailed Description

template<class EquationOfState, int PolySize = 8>
class Foam::ePolynomialThermo< EquationOfState, PolySize >

Internal energy based thermodynamics package using a polynomial function of temperature for the constant heat capacity at constant volume: 

    Cv = CvCoeffs[0] + CvCoeffs[1]*T + CvCoeffs[2]*sqr(T)
       + CvCoeffs[3]*pow3(T) + CvCoeffs[4]*pow4(T)
       + CvCoeffs[5]*pow(T, 5) + CvCoeffs[6]*pow(T, 6)
       + CvCoeffs[7]*pow(T, 7)

The polynomial function is templated on the order of the polynomial which defaults to 8.

Usage
Property Description
Hf Heat of formation
Sf Standard entropy
CvCoeffs<8> Specific heat at constant volume polynomial coeffs

Example of the specification of the thermodynamic properties: 

    thermodynamics
    {
        Hf              0;
        Sf              0;
        CvCoeffs<8>     (1000 -0.05 0.003 0 0 0 0 0);
    }

Note: Specific heat at constant volume polynomial coefficients evaluate to an expression in [J/kg/K].
