Detailed Description

This boundary condition provides a velocity boundary condition for multiphase flow based on a user-specified volumetric flow rate.

The flow rate is made proportional to the phase fraction alpha at each face of the patch and alpha is ensured to be bound between 0 and 1.

Usage

Property	Description	Required	Default value
`flowRate`	volumetric flow rate [m^3/s]	yes
`alpha`	phase-fraction field	yes

Example of the boundary condition specification:

    <patchName>
    {
        type            variableHeightFlowRateInletVelocity;
        flowRate        0.2;
        alpha           alpha.water;
        value           uniform (0 0 0); // placeholder
    }

The flowRate entry is a Function1 of time, see Foam::Function1s.

Note:

the value is positive into the domain
may not work correctly for transonic inlets
strange behaviour with potentialFoam since the momentum equation is not solved
