Detailed Description

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

\[ p_rgh = p - \rho g.(h - hRef) \]

\[ p = p0 - 0.5 \rho |U|^2 \]

where

\( p_rgh \)	=	Pseudo hydrostatic pressure [Pa]
\( p \)	=	Static pressure [Pa]
\( p0 \)	=	Total pressure [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
`p0`	Total pressure	yes

Example of the boundary condition specification:

    <patchName>
    {
        type            prghTotalPressure;
        p0              uniform 0;
    }
