24 Class
25  Foam::fixedPressureCompressibleDensityFvPatchScalarField
26 
27 Description
28  This boundary condition calculates a (liquid) compressible density as a
29  function of pressure and fluid properties:
30 
31  \f[
32  \rho = \rho_{l,sat} + \psi_l*(p - p_{sat})
33  \f]
34 
35  where
36 
37  \vartable
38  \rho | density [kg/m^3]
39  \rho_{l,sat} | saturation liquid density [kg/m^3]
40  \psi_l | liquid compressibility
41  p | pressure [Pa]
42  p_{sat} | saturation pressure [Pa]
43  \endvartable
44 
45  The variables \c rholSat, \c pSat and \c psil are retrieved from the
46  \c thermodynamicProperties dictionary.
47 
48 Usage
49  \table
50  Property | Description | Required | Default value
51  p | pressure field name | no | p
52  \endtable
53 
54  Example of the boundary condition specification:
