Hi all,
Does anyone know how to define hPolynomial in the thermo choice (within the thermophysicalProperties file) ?
An example file would be veeeery helpfull

Hi again,

I've found one example that I post right here for anyone who would need.

 
thermoType
{
    type            heRhoThermo;
    mixture         pureMixture;
    transport       polynomial;
    thermo          hPolynomial;
    equationOfState icoPolynomial;
    specie          specie;
    energy          sensibleEnthalpy;
}

dpdt            no; 

// Cooler - water
// Data from H2O_NIST
// Values for 590 < T < 619 (K)
// Data for viscosity (mu), kappa, Cp and rho were fitted for polynomials
// of 6th order.

mixture
{
    specie
    {
        // Water mol weight [g/mol]
        nMoles          1;
        molWeight       18.02; 
    }

    transport
    {
      // *** polynomial
      // mu [Pa.s]
      // kappa [W/m/K]

     muCoeffs<8> (0.477756 -0.00337294 7.80884e-06 -2.59645e-09 -1.64495e-11 2.49614e-14 -1.10764e-17 0);
     kappaCoeffs<8> (1456.92 -10.2864 0.0238197 -7.80437e-06 -5.02923e-08 7.60632e-11 -3.36662e-14 0);
    }

    thermodynamics
    {
      // *** hPolynomial
      // Cp = [J/kg/K]
      Hf  0;
      Sf  0;
      CpCoeffs<8> (-7.56975e08 5.24432e06 -11530.9 1.22828 0.0308639 -4.34995e-05 1.88346e-08 0);
    }

    equationOfState
    {
      // *** icoPolynomial
      // rho = [Kg/m^3]
      rhoCoeffs<8> (4.02745e06 -27520.6 57.8951 0.00610405 -0.000187407 2.52756e-07 -1.08057e-10 0);
    }
}

One more question :
Do you know if in the code in the thermodynamics definition:

Hf 0;
Sf 0;

are some placeholders or not ?

Thank you,

Adrien
