Detailed Description

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

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

where

$ p_rgh $ = Pseudo hydrostatic pressure [Pa]
$ p $ = Static 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]


Patch usage

Property Description Required Default value
rho rho field name no rho
p static pressure yes

Example of the boundary condition specification:

    myPatch
    {
        type            prghPressure;
        rho             rho;
        p               uniform 0;
        value           uniform 0; // optional initial value
    }
