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;
    }
