Detailed Description

This boundary condition calculates a (liquid) compressible density as a function of pressure and fluid properties:

\[ \rho = \rho_{l,sat} + \psi_l*(p - p_{sat}) \]

where

$ \rho $ = density [kg/m3]
$ \rho_{l,sat} $ = saturation liquid density [kg/m3]
$ \psi_l $ = liquid compressibility
$ p $ = pressure [Pa]
$ p_{sat} $ = saturation pressure [Pa]

The variables rholSat, pSat and psil are retrieved from the thermodynamicProperties dictionary.


Patch usage

Property Description Required Default value
p pressure field name no p

Example of the boundary condition specification:

    myPatch
    {
        type        fixedPressureCompressibleDensity;
        p           p;
        value       uniform 1;
    }
