Detailed Description

template<class Specie>
class Foam::perfectFluid< Specie >

Simple extension of the perfect gas equation of state to liquids by the addition of a constant density off-set:

    rho = rho0 + p/(R*T)

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

This equation of state is rather inaccurate and has been superseded by rPolynomial which is much more accurate and supports mixtures.

Usage

Property	Description
`rho0`	Reference density
`R`	Fluid constant

Example specification of the perfectFluid equation of state:

    equationOfState
    {
        rho0        1000;
        R           100;
    }
