Detailed Description

template<class Specie>
class Foam::rPolynomial< Specie >

Reciprocal polynomial equation of state for liquids and solids.

    1/rho = C[0] + C[1]*T + C[2]*sqr(T) - C[3]*p - C[4]*p*T

This polynomial for the reciprocal of the density provides a much better fit than the equivalent polynomial for the density and has the advantage that it support coefficient mixing to support liquid and solid mixtures in an efficient manner.

Usage

Property	Description
`C`	Density polynomial coefficients

Example specification of the rPolynomial equation of state for pure water:

    equationOfState
    {
        C (0.001278 -2.1055e-06 3.9689e-09 4.3772e-13 -2.0225e-16);
    }

Note: This fit is based on the small amount of data which is freely available for the range 20-65degC and 1-100bar.
