Detailed Description

This boundary condition adjusts the velocity for the given phase to achieve the specified mean thus causing the phase-fraction to adjust according to the mass flow rate.

Typical usage is as the outlet condition for a towing-tank ship simulation to maintain the outlet water level at the level as the inlet.


Patch usage

Property Description Required Default value
Umean mean velocity normal to the boundary [m/s] yes
alpha phase-fraction field yes

Example of the boundary condition specification:

    myPatch
    {
        type            outletPhaseMeanVelocity;
        Umean           1.2;
        alpha           alpha.water;
        value           uniform (1.2 0 0);
    }
