Class
    Foam::rhoTabulated
 
Description
    Incompressible of equation of state using uniform tabulated
    density vs pressure and temperature.
 
    Thermodynamic contributions derived from tabulated density data are not
    sufficiently accurate and hence the h, Cp, e, Cv, sp, sv and CpMCv are not
    implemented.  Thus this equation of state should be used in conjunction with
    hTabulated or eTabulated thermodynamics in which both the energy and heat
    capacity are tabulated w.r.t. pressure and temperature avoiding the need
    for equation of state contributions.
 
Usage
    \table
        Property     | Description
        rho          | Density vs pressure and temperature table
    \endtable
 
    Example of the specification of the equation of state:
    \verbatim
    equationOfState
    {
        rho
        {
            pLow    1e4;
            pHigh   5e5;
 
            Tlow    200;
            Thigh   1500;
 
            values
            <m> <n>
            (
                (..........)
                .
                .
                .
                (..........)
            );
        }
    }
