Detailed Description

template<class Specie, int PolySize = 8>
class Foam::icoPolynomial< Specie, PolySize >

Incompressible, polynomial form of equation of state, using a polynomial function for density.

Coefficient mixing is very inaccurate and not supported, so this equation of state is not applicable to mixtures.

Usage
Property Description
rhoCoeffs<8> Density polynomial coefficients

Example of the specification of the equation of state:

    equationOfState
    {
        rhoCoeffs<8>    ( 1000 -0.05 0.003 0 0 0 0 0 );
    }

The polynomial expression is evaluated as so:

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