Detailed Description

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

Thermodynamics package templated on the equation of state, using polynomial functions for cp, h and s.

Polynomials for h and s derived from cp.

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 );
    }

The polynomial expression is evaluated as so:

\[ Cp = 1000 - 0.05 T + 0.003 T^2 \]

Note
  • Heat of formation is inputted in [J/kg], but internally uses [J/kmol]
  • Standard entropy is inputted in [J/kg/K], but internally uses [J/kmol/K]
  • Specific heat at constant pressure polynomial coefficients evaluate to an expression in [J/kg/K].
