Density, \(\rho\) [kg/m\(^3\)]

\[\rho = \rho_0 + \frac{p}{R T}\]

Entropy, \(S\) [J/kg/K ]

\[S = -R \ln \left( \frac{p}{p_{\std}} \right)\]

Compressibility, \(\psi\) [s\(^2\)/m\(^2\)]

\[\psi = \frac{1}{R T}\]

Usage

The perfectFluid equation of state is specified as:

equationOfState
{
    R           <scalar>;
    rho0        <scalar>;
}

Where

  • R : Fluid constant [J/kg/K]
  • rho0 : Reference density [kg/m\(^3\)]
