Density, \(\rho\) [kg/m\(^3\)]
\[\rho = \rho_0 \frac{p + B}{p_0 + B}^{\frac{1}{\gamma}}\]Entropy, \(S\) [J/kg/K ]
\[S = -(p_0 + B)^\frac{1}{\gamma} \frac{(p + B)^{1 - \frac{1}{\gamma}} - (P_{\std} + B)^n}{\rho_0 T (1 - \frac{1}{\gamma})}\]Compressibility, \(\psi\) [s\(^2\)/m\(^2\)]
\[\psi = \frac{\rho_0}{\gamma(p_0 + B)} \frac{p + B}{p_0 + B}^{\frac{1}{\gamma} - 1}\]Usage🔗
The adiabaticPerfectFluid equation of state is specified as:
equationOfState
{
p0 <scalar>;
rho0 <scalar>;
gamma <scalar>;
B <scalar>;
}
Where
-
p0: Reference pressure [Pa] -
rho0: Reference density [kg/m\(^3\)] -
gamma: Isentropic exponent [-] -
B: Pressure offset for a stiffened gas [Pa]
