Equation of state for liquid
 
Hi all! Please, help! I can't clear up the following questions: 1.Do ANSYS FLOTRAN permit to simulate the compressible liquid flow (not gas)? 2.What liquid state equation can be used for simulation? Thank you.

What about


\begin{equation}
\frac{d\varrho}{dp}\,=\,\frac{1}{a^2}
\end{equation}

\begin{equation}
\varrho\,=\,\varrho_0\,+\,\frac{p_{rel}}{a^2}
\end{equation}


with a = speed of sound

Thank you for help. As far as I know this linear dependence rho(p) can't be used if pressure reaches 1 GPa. What should I do in this case? By the way, how to apply speed of sound in Flotran?
