Detailed Description

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

Enthalpy based thermodynamics package using a polynomial function of temperature for the constant heat capacity at constant pressure: 

    Cp = a0 + a1*T + a2*sqr(T) + a3*pow3(T) + a4*pow4(T)
       + a5*pow(T, 5) + a6*pow(T, 6) + a7*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
CpCoeffs<8> Specific heat at constant pressure polynomial coeffs

Example of the specification of the thermodynamic properties: 

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

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