Detailed Description

This boundary condition provides a phase-based hydrostatic pressure condition, calculated as:

\[ p_{hyd} = p_{ref} + \rho g (x - x_{ref}) \]

where

$ p_{hyd} $ = hyrostatic pressure [Pa]
$ p_{ref} $ = reference pressure [Pa]
$ x_{ref} $ = reference point in Cartesian co-ordinates
$ \rho $ = density (assumed uniform)
$ g $ = acceleration due to gravity [m/s^2]

The values are assigned according to the phase-fraction field:

  • 1: apply $fp_{hyd}$f
  • 0: apply a zero-gradient condition
Usage
Property Description Required Default value
phaseFraction phase-fraction field name no alpha
rho density field name no rho
pRefValue reference pressure [Pa] yes
pRefPoint reference pressure location yes

Example of the boundary condition specification:

    <patchName>
    {
        type            phaseHydrostaticPressure;
        phaseFraction   alpha1;
        rho             rho;
        pRefValue       1e5;
        pRefPoint       (0 0 0);
        value           uniform 0; // optional initial value
    }
