Detailed Description

This boundary condition provides static pressure condition for p_rgh, calculated as:

\[ p_rgh = ph_rgh - 0.5 \rho |U|^2 \]

where

\( p_rgh \) = Pressure: \( \rho g (h - h_{ref}) \) [Pa]
\( ph_rgh \) = Hydrostatic pressure: \( \rho g (h - h_{ref}) \) [Pa]
\( h \) = Height in the opposite direction to gravity
\( hRef \) = Reference height in the opposite direction to gravity
\( \rho \) = Density
\( g \) = Acceleration due to gravity [m/s^2]
Usage
Property Description Required Default value
U Velocity field name no U
phi Flux field name no phi
rho Density field name no rho
ph_rgh ph_rgh field name no ph_rgh
value Patch face values yes

Example of the boundary condition specification:

    <patchName>
    {
        type            prghTotalHydrostaticPressure;
        value           uniform 0;
    }
